ABSTRACT:
The invention provides a liquid crystal device including a first substrate and a second substrate opposing each other, a plurality of pixel electrodes disposed on the first substrate in a matrix, drive voltages having opposite polarities with respect to a reference voltage being applied to adjacent pixels, a common electrode disposed on the second substrate, and an electro-optical substance disposed between the first substrate and the second substrate. The device can also include a second alignment layer disposed on the second substrate and subjected to a uniform alignment operation, a first alignment layer formed of an alignment material on the first substrate subjected to alignment operations so that the alignment operation at strip areas and the alignment operation at areas other than the strip areas are different. Each strip area can be disposed near a first edge of its corresponding pixel electrode and is an area where the electro-optical substance is affected by an electric field produced between the adjacent pixel electrodes by the drive voltages having opposite polarities. By this, the aperture ratio can be increased by reducing reverse tilts caused by the effects of the transverse electric field.
