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. |

1. An electro optical device comprising:
a pixel array constituted by pixels arranged in matrix, each pixel including four subpixels, the four subpixels including subpixels of colors of R (Red), G (Green) and B (Blue), and a subpixel of a similar color to a specific color, the specific color being a color of subpixel including a light emitting material having a shortest lifetime among the light emitting materials included in the subpixels of colors of R, G and B, respectively, and the four subpixels being arranged in two rows and two columns; and a control unit that executes switching between a 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 a first luminance ratio, and a second driving condition in which both the subpixel of the specific color and the subpixel of the similar color are driven to emit light with a second luminance ratio different from the first luminance ratio, as conditions for driving the pixels, in accordance with a color of a pixel to be displayed, and wherein each of the pixels includes:
a first subpixel having a highest emission luminance and a second subpixel having a second highest emission luminance among subpixels needed to display a white color, both the first subpixel and the second subpixel being arranged on one diagonal line of the pixel; anda third subpixel having a third highest emission luminance and a fourth subpixel having a lowest emission luminance, both the third subpixel and the fourth subpixel being arranged on another diagonal line of the pixel. |
