Abstract
Abstract Arrangements of picture-element electrodes of a color liquid-crystal display apparatus. In a color liquid-crystal display apparatus using mosaic arrangements, the same color of picture elements which are driven by the same signal electrode are alternately arranged right and left. Accordingly, all the necessary thing is that the same color of picture signal is applied upon the same signal electrode in spite of the mosaic arrangement. Thus, a circuit is rendered unnecessary which switches a color image signal of an analog line memory, so that the driving circuit is extremely simplified.
