1. A liquid crystal device, comprising:
- an array substrate including a plurality of pixel electrodes arranged in a matrix manner;
an opposed substrate including a conductive light shielding film having openings at positions opposing the pixel electrodes; and
a liquid crystal layer interposed between the substrates, the liquid crystal layer being formed of liquid crystal having negative dielectric anisotropy exhibiting homeotropic alignment in the initial alignment state, and the liquid crystal being controlled in alignment by an electric field developed by difference in electric potential between the pixel electrodes of the array substrate and the light shielding film of the opposed substrate.

Abstract
To achieve clear image display without providing a feeling of roughness by fixing the position where disclination is generated in a liquid crystal device of a homeotropic alignment type, a conductive light shielding film provided on the side of an opposed substrate as a common electrode to drive a liquid crystal layer by pixel electrodes of an array substrate and the light shielding film of the opposed substrate.
