摘要： PURPOSE:To improve a display grade and reliability by decreasing the number of stages to reduce costs and further, inevitably decreasing the chances that foreign matter intrude into respective thin films by the decreased number of stages. CONSTITUTION:Transparent electrode layers 4, 4 consisting of ITO films are formed on the opposite surfaces of plastic substrates 3, 3 coated with hard coating films 2. SiOx films 5, 5 which have a gas shielding capacity and have an insulating characteristic are formed by sputtering on these transparent electrode layers 4, 4. Oriented films 6, 6 are formed on these SiOx films 5, 5 and a liquid crystal layer 8 is held between the plastic substrates 3, 3. Then, the role of the top coats of the conventional elements is commonly played by the SiOx films 5, 5 by forming the SiOx films 5, 5 on the transparent electrode layers 4, 4. The integration of the top coating films and the gas shielding films is thus possible.

摘要： PURPOSE:To provide the liquid crystal display device which is high in display quality and reliability. CONSTITUTION:Hard coat films 3a-3d are formed on both surfaces of plastic substrates 2a and 2b and SiOx films 4a and 4b are formed by sputtering on the opposite surfaces of the plastic substrates 2a and 2b. Transparent electrode layers 5a and 5b of ITO film and orienting films 6a and 6b are formed in order on the SiOx films 4a and 43b and a liquid crystal layer 8 is interposed between the plastic substrates 2a and 2b. The contact between the plastic substrates 2a and 2b is improved to reduce the cracking of the transparent electrode layers 5a and 5b, and the gas shielding ability of the plastic substrates 2a and 2b is greatly improved to reduce the generation of air bubbles in the liquid crystal layer 8.

摘要： PURPOSE:To improve the reliability of the liquid crystal display element. CONSTITUTION:A parting process for forming an injection hole through which a liquid crystal material is injected is performed by dicing an upper plastic substrate 2 and a lower plastic substrate 3 by using a dicing blade 1 to make cut so that specific thickness is left and then breaking them. Therefore, the injection hole is never exposed to the outside during the dicing process, so cutting chips 4, etc., produced by the dicing process are prevented from entering the liquid crystal display element and the injection hole is never clogged with the cutting chips 4, etc.

摘要： PURPOSE:To reduce the size and weight and to obtain excellent contrast characteristics by providing an optical compensation member which is made of a uniaxially drawn high polymer sheet body and arranged on one side of a liquid crystal display element to compensate the birefringence of liquid crystal, a 1/4-wavelength plate, and a 2nd polarizing member. CONSTITUTION:When the optical compensating member 11 made of the uniaxially drawn high polymer sheet body is used on one side of the liquid crystal display element 4, a light display and a dark display are both made by extracting only linear polarized light by a projection-side polarizing plate 13 from elliptic polarized light from the liquid crystal display element 4. Therefore, when a voltage less than a display threshold value is applied to the liquid crystal display element 4 to make, for example, the light display, elliptic polarized light beams with wavelengths corresponding to red, green, and blue have elliptic azimuths almost in the same direction right under the projection side polarizing plate and the shape of the elliptic polarized light approximates linear polarized light relatively. Consequently, the excellent contrast with the small- sized, lightweight constitution is obtained.

SOLUTION: After an oriented film 4 is formed on the whole surface of an electrode substrate 1 and processed by orientation by a rubbing method, the oriented film 4 formed on external connected terminals of the liquid crystal display panel is removed by irradiating ultraviolet laser rays 5, and the external connection terminals and the connection terminals of external parts constituting the liquid crystal display device are electrically connected. Further, an energy density of the ultraviolet rays 5 is adjusted by an attenuator 9 to remove the oriented film 4. Further, the energy density of the ultraviolet rays 5 is adjusted to a range of 110-210 mJ/cm to remove the oriented film 4.

摘要： PURPOSE:To enable a batch process for cleaning plural transparent substrates, to shorten the cleaning time, and to stabilize the operation flow by holding the transparent substrates in a curved state. CONSTITUTION:Both the right and left end sides of a transparent substrate 4 are fitted in both side parts fitting grooves 21. At this time, the isolation distance between the right and left tips of both side part fitting grooves 21 is smaller than the right-left width of the transparent substrate 4, so both the right and left end sides of the transparent substrate 4 are pushed to shrink and naturally curve. Then the upper-end center part or lower-end center part of the transparent electrode 4 is fitted in a center fitting groove 22. At this time, the center fitting part 22 is arranged while shifting in the curving direction of the transparent substrate 4 from the mid-point of a segment having end points at both the right and left side fitting grooves 21 corresponding to the center fitting part, so the transparent substrate 4 is held in the curved shape. Then the transparent electrode 4 is to restore itself elastically to a flat shape and the fixation by both the fitting grooves 21 and 22 is strengthened. Plural transparent substrates 4 are held in one cleaning cassette to enable the cleaning batch process.

摘要： PURPOSE:To uniformly maintain a cell thickness even if mechanical and electrical forces act on the cell and to prevent the degradation in quality by spraying hard plastic beads on the insulating film of one substrate and baking the beads, thereby fixing the beads as the spacers in the cell. CONSTITUTION:The insulating film 4 is provided on the upper substrate 2 provided with transparent electrodes 3 and the hard plastic beads 5 are sprayed on the insulating film 4 by a solvent consisting of a liquid mixture composed of alcohol and water and are baked at a prescribed temp. An oriented film 6 is thereafter formed, baked and subjected to an orientation treatment by rubbing. The upper and lower substrates 2, 2 are stuck to each other and a liquid crystal material 8 is injected therebetween. Namely, the uniform cell gap is obtd. by using the hard plastic beads 5. Since the hard plastic beads 5 are fixed by the insulating film 4 and are provided only on the one side substrate 2 and, therefore, there is no need for a special adhesive in the stage and the clouding of the insulating film is obviated. In addition, the movement of the plastic beads by the mechanical and electrical stresses does not arise.
