Abstract
A multi-primary color display device is capable of handling an increased number of primary colors for color image display with a reduced number of external parts, with reduced increase in the amount of drive circuit and reduced increase in operating speed. An active matrix liquid crystal panel includes a display section constituted by pixel formation portions, each made of four sub pixel-formation portions which handle four primary colors. These four sub pixel-formation portions are arranged in a 2×2 matrix pattern. With such a pixel configuration, a source driver drives as many as M source lines, which is two times the number M of pixels arranged in a horizontal direction. A gate driver is formed on the liquid crystal panel integrally with pixel circuit in the display section, and drives as many as N gate lines, which is two times the number N of the pixels arranged in a vertical direction.
