Display device

A display device, comprising:

• a plurality of blocks of pixels each of which includes subpixels respectively of three colors, each of said blocks including pixels in a form of a matrix having N rows and M columns;
• a subpixel electrode disposed in each said pixel;
• a display element disposed in said each subpixel, said element operating according to a voltage on said subpixel electrode;
• a scanning line driving circuit for supplying a scanning signal to scanning lines arranged substantially parallel to each other;
• a discriminating signal line driving circuit for supplying a discriminating signal to discriminating signal lines arranged substantially vertical to said scanning lines;
• holding means for holding in said pixel a discriminating signal from said discriminating line;
• a gradation voltage line driving circuit for supplying a gradation voltage to Ma gradation voltage lines of said gradation voltage lines for supplying a gradation voltage to each said subpixel, said Ma gradation voltage lines being commonly connected (Ma is an integer;
• M≧Ma≧2) for said subpixels respectively of three colors of red, green, and blue in a direction of the column;
• a circuit for selecting a gradation voltage according to said discriminating signal;
• and
• a switch for applying the gradation voltage selected by said selecting circuit to said subpixel electrode.
