Patent ID: 8922603

Claim:
A multi-primary color display device for displaying color images based on four or a greater predetermined number of primary colors, comprising: a display panel including a plurality of pixel formation portions arranged in a matrix pattern, a plurality of data signal lines and a plurality of scanning signal lines crossing the data signal lines; a data signal line drive circuit for applying a plurality of data signals which represent an image to be displayed, to the data signal lines; and a scanning signal line drive circuit for selectively activating the scanning signal lines; wherein the scanning signal line drive circuit is formed on the display panel; each pixel formation portion includes a predetermined number of sub pixel-formation portions for forming subpixels of said predetermined number of primary colors; the predetermined number of sub pixel-formation portions included in each pixel formation portion are arranged in a matrix pattern consisting of a plurality of rows extending in a direction in which the scanning signal lines extend and a plurality of columns extending in a direction in which the data signal lines extend; each of the sub pixel-formation portions included in the pixel formation portions corresponds to one of intersections made by the data signal lines and the scanning signal lines, and is connected to the data signal line and the scanning signal line which pass through said intersection; each sub pixel-formation portion includes a predetermined capacitance, captures and supplies a voltage in the data signal line which passes through the corresponding intersection to the predetermined capacitance when the corresponding scanning signal line is activated; and the scanning signal line drive circuit sequentially activates the scanning signal lines for a predetermined period so that each sub pixel-formation portion captures the voltage in the data signal line as a subpixel value of the image to be displayed, while also activating each scanning signal line for a predetermined period preceding said period of sequential activation by as many periods as a vertical color cyclic number, the vertical color cyclic number being defined as a quantity of the sub pixel-formation portions within each pixel formation portion in a direction in which the data signal lines extend.
