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.
