摘要： In a pixel array, pixels are two-dimensionally arranged, each of the pixels including a subpixel of the first color having a highest luminosity factor, a subpixel of the second color and a subpixel of the third color having a lowest luminosity factor. A circuit element in each of subpixels of the first color to the third color in each of the pixels is arranged in a row direction. A light emitting region of a subpixel of the first color and a light emitting region of a subpixel of the second color are arranged in the first direction inclined to the row direction. A light emitting region of a subpixel of the third color is arranged in the second direction orthogonal to the first direction, with respect to the light emitting region of the subpixel of the first color and the light emitting region of the subpixel of the second color.

摘要： 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.
