ABSTRACT:
Non-uniformity of a cell gap of a liquid crystal panel is suppressed from affecting display adversely. Concentric interference fringes are unavoidably formed in a liquid crystal cell in which liquid crystal is sealed and the cell gap is maintained by a sealing member without using scattered spacers. Then, peripheral driving circuits are provided in regions where the interference fringes exist and a pixel matrix circuit is disposed in a region where no interference fringe exists. It is then possible to suppress the cell gap from affecting the display by determining the circuit configuration by parameterizing the interference fringes as described above.
