ABSTRACT:
A reflective liquid crystal display has a matrix of pixels formed on a semiconductor substrate. The pixels include pixels A aligned in pixel-A columns and pixels B aligned in pixel-B columns. The pixel-A and pixel-B columns are alternated in a horizontal direction. A first fixed potential line (well line) is formed along each of the pixel-A columns and is connected to well regions of the pixels in the pixel-A column, to supply a first fixed potential (well potential) to the pixels in the pixel-A column and to the pixels in an adjacent one of the pixel-B columns through the well regions of the pixel-A column. A second fixed potential line (common line) is formed along each of the pixel-B columns and is connected to diffusion capacitor electrodes formed on hold capacitors of the pixels in the pixel-B column, to supply a second fixed potential (common potential) to the pixels in the pixel-B column and to the pixels in an adjacent one of the pixel-A columns through the diffusion capacitor electrodes of the pixel-B column.
