VERTICALLY ALIGNED LIQUID CRYSTAL DISPLAY DEVICE
First Claim
1. A liquid crystal display device comprising:
- a pair of substrates facing each other with a predetermined gap provided therebetween;
an opposing electrode formed by a conductive film on one of opposing inner surfaces of the pair of substrates;
a plurality of pixel electrodes formed by conductive films arrayed in a matrix form on an other one of the opposing inner surfaces of the pair of substrates, a plurality of pixels being defined by those areas of the plurality of pixel electrodes which face the opposing electrode;
vertical alignment films respectively provided on the inner surfaces of the pair of substrates in such a way as to respectively cover the opposing electrode and the pixel electrodes;
a liquid crystal layer having a negative dielectric anisotropy sealed between the pair of substrates; and
cutaway portions each provided, for each of the pixels, at least one of the pixel electrode and the opposing electrode and obtained by cutting away a part of the associated conductive film to define an alignment center of liquid crystal molecules in the each pixel.
