    Abstract: An electro optical device has a pixel array constituted by pixels arranged in matrix, each pixel including four subpixels, the four subpixels including RGB subpixels and a subpixel of a similar color to a specific color among RGB, and the four subpixels being arranged in two rows and two columns. In each pixel, a first subpixel having the highest emission luminance and a second subpixel having the second highest emission luminance among subpixels needed for white display are arranged on one diagonal line of the pixel, and the other subpixels are arranged on the other diagonal line. The electro optical device has a control unit that executes switching between a first driving condition and a second driving condition in accordance with a color of a pixel to be displayed, the first driving condition in which both the subpixel of the specific color and the subpixel of the similar color are driven to emit light with the first luminance ratio, and the second driving condition in which both the subpixels of the specific color and the similar color are driven to emit light with the second luminance ratio.

    Abstract: In a pixel array in which rectangular pixels, each enclosing a subpixel of the first color (SP1) which has the highest luminosity factor, a subpixel of the second color (SP2) and a subpixel of the third color (SP3) which has the lowest luminosity factor, are two-dimensionally arranged, SP2 includes first and second portions respectively near two corners adjacent to each other in the first direction of the pixel, SP3 includes first and second portions near other two corners adjacent each other in the first direction of the rectangular pixel, and SP1 is located at a middle part including a center of gravity of the rectangular pixel. SP3 has a larger area than each of SP1 and SP2. In the second direction orthogonal to the first direction, SP2 and SP3 are widest near a pixel boundary in the first direction, SP1 is widest near the center of gravity in the pixel.
