摘要： There is provided a high-definition liquid crystal display device that can prevent flicker due to a reduction in the pixel potential in a low-frequency drive of about 10 Hz to reduce power consumption. The pixel has a TFT formed of Poly-Si as a switching element. In the pixel, a capacitance insulating film is formed on a planar first electrode on which a comb-shaped second electrode is fanned. When the film thickness of the insulating film is d and the dielectric constant at 10 Hz frequency is ∈, it is given that ∈d≥5×10−6 m at 10 Hz frequency. The capacitance insulating film does not have a hysteresis characteristic. The refractive index of the capacitance insulating film with respect to a light of a wavelength of 632.8 nm is 1.7 to 2.0.

摘要： To prevent dark unevenness at the corner portion of a screen, a provided is a liquid crystal display including a first pixel formed with a pixel electrode at a first angle in a Y-direction, wherein the pixel electrodes of top, bottom, left, and right adjacent pixels to the first pixel are at a second angle in a Y-direction. The absolute value of the first angle is equal to the absolute value of the second angle, and a sign of the first angle is opposite to a sign of the second angle The rotation direction of a liquid crystal when a voltage is applied to the pixel electrode is in the opposite directions between the adjacent pixels. Thus, it is possible to prevent ions included in the liquid crystal from flowing on the peripheral portion of a display region to prevent dark unevenness at the corner portion of the screen.

摘要： In an LCD device, the slope angle of a wall surface of a wall structure (wall-surface slope angle) is varied in accordance with the angle formed between the wall structure and an alignment treatment direction (alignment treatment angle). At places where the alignment treatment angle is small, the wall-surface slope angle is made larger; conversely, at places where the alignment treatment angle is large, the wall-surface slope angle is made smaller.

摘要： A liquid crystal display device includes a TFT substrate, a CF substrate, and a liquid crystal interposed between the TFT substrate and the CF substrate, and drives the liquid crystal in a horizontal electric field. The TFT substrate includes a recess, and the CF substrate includes a columnar protrusion. The protrusion of the CF substrate is fitted to the recess of the TFT substrate so as to function as a stopper for preventing a positional gap between the TFT substrate and the CF substrate.
