SOLUTION: In this color imaging method, at least one color of yellow of an ink set for inkjet recording using at least three or more different color inks excepting black has an absorption wavelength in the 400-500 nm range and a main reflective wavelength in the 500-700 nm range and contains a fluorescent ink. In addition, in this method, the variability of the inner angle of the chromatic triangle, in a hue chart, formed of a magenta dye having an absorption wavelength in the 500-600 nm range and a main reflective wavelength in the 600-700 nm range and a cyan dye having an absorption wavelength in the 550-700 nm range and a main reflective wavelength in the 400-550 nm range, is set lower than 29°.

摘要： PROBLEM TO BE SOLVED: To provide a base board carrying tool capable of optical alignment, and causing no pollution on the reverse side of a base board by the water remainder and a solvent even in a wet process such as a cleaning process. SOLUTION: This base board carrying tool 1 carries the base board in a manufacturing process of a liquid crystal display element in a state of sticking the base board to a surface. A pressure sensitive adhesive layer 2 for adhesively holding the base board is adhered to a surface of a plate-like transparent support 4 by an adhesive 3. A light transmissive hole 5 for alignment is formed in the pressure sensitive adhesive layer 2 and the adhesive 3 except for the support 4 in a corresponding place of an alignment mark formed on the base board stuck to the pressure sensitive adhesive layer 2.

摘要： PROBLEM TO BE SOLVED: To provide a liquid crystal display element manufacturing method and a liquid crystal display element manufacturing device capable of adsorbing and fixing a substrate of a liquid crystal display element in a flat state without deviating positionally and with sufficient force and without leaving the deformation of the substrate. SOLUTION: An insulated substrate 5 is mounted on a stage 1 and at the same time, attracting force is made to act on the substrate 5 through second suction ports 3 by turning a valve 15 of a blower to previously be operated 16 ON. Then, by operating a vacuum pump 10 and valve 9, attracting force is made to act on nearlly the all areas of the central part of the substrate 5 through the first area 2a of first suction ports 2 and next, the first area 2a and a second area 2b and moreover, the first area 2a, the second are 2b and a third area 2c. Thus, the deformation of the substrate 5 is successively moved to a non-suction area and the deformation is collected in the vicinity of the outer peripheral part of the substrate finally and at this timing, the attracting force action on the vicinity of the outer peripheral parts from the second suction ports 3 is released by turning the valve 15 of the blower 16 OFF.

摘要： PROBLEM TO BE SOLVED: To increase the area proportion of a color filter layer 10B of blue approximating the complementary color of yellow relatively to those of other color filter layers 10R and 10G of red and green in the case that a transparent plastic substrate is made yellowish by passing through a manufacturing process and to realize transmission color display superior in color reproducibility by approximating reflected light and transmitted light to white light at the time of white display in the case of reflection display and transmission display. SOLUTION: An aperture part 20B of a blue color filter layer 10B is made smaller than aperture parts 20R and 20G of red and green color filter layers 10R and 10G. An aperture part 21B of a reflection film 11 in a blue pixel area is made larger than aperture parts 21R and 21G of the reflection film 11 in the other red and green pixel areas. Consequently, the blue color filter layer 10B out of red, green, and blue color filter layers 10R, 10G, and 10B has the largest area to color the reflected light and the transmitted light.

摘要： PURPOSE:To obtain a dense and uniform transparent conductive film and to prevent production of cracks in the transparent conductive film by forming a transparent conductive film on the surface of a molding die to be used to mold a resin substrate, patterning the film, and then molding a transparent resin in this molding die. CONSTITUTION:A transparent conductive film 3 is formed on the molding surface of a surface-treated layer 2 of the one molding die 1. The transparent conductive film 3 is patterned into a specified electrode pattern. Then the molding die 1 is set in the molding position and a transparent resin is supplied to fill the molding space. Then the molded body of the transparent resin is released with the transparent conductive film 3 from the molding surface to obtain a resin substrate having electrodes. Namely, the transparent conductive film 3 is formed on the surface of the molding die 1, so that the temp. condition for the formation of the film can be determined at a higher temp. according to the heat resistance of the molding die 1. Therefore, the dense and uniform transparent conductive film 3 is obtd. Since the transparent conductive film 3 is already patterned into small pieces, production of cracks is decreased.

摘要： PURPOSE:To improve the production yield of the liquid crystal display elements and to reduce the cost of production by effectively suppressing peeling of sealing materials from the outer peripheral parts of substrates which arises at the time of producing a liquid crystal display plate by sticking a pair of the plastic substrates to each other. CONSTITUTION:An ITO film 2 is first formed on the plastic substrate 1. Oriented films 3, 3 are then formed thereon and dummy oriented films 3a... are formed in the outer peripheral parts of the plastic substrate 1. After the oriented films 3, 3 are subjected to an orientation treatment, sealing parts 4, 4 are formed on the oriented films 3, 3 and dummy sealing parts 4a... are formed on these dummy oriented films 3a.... A pair of the plastic substrates 1, 1 formed in such a manner are stuck to each other to form the liquid crystal display plate. This liquid crystal display plate is parted along prescribed parting lines R and the parts stuck to each other by the dummy sealing parts 4a... are discarded, by which the liquid crystal display elements are produced.
