ABSTRACT:
A matrix-addressed type liquid crystal display apparatus having switching devices such as TFTs is provided, featuring that an increased effective voltage can be applied without causing hysteresis in V-T characteristics. Namely, by substantially increasing a value of an applicable voltage in excess of which a display defect starts to appear, a high numerical aperture and a high contrast ratio have been achieved at the same time. In the LCD apparatus of the present invention, a gap between adjacent reverse tilt domains each formed in a portion of a pixel which is arranged corresponding to an arbitrary pixel electrode becomes broader than a minimum gap between adjacent pixel electrodes corresponding thereto, or a thickness of a liquid crystal cell in the portion between adjacent reverse tilt domains is set thinner than a thickness of a liquid crystal cell in the portion of the pixel.
