The display device 500 illustrated as an example in
When every three pixels 532 function as one pixel, full-color display can be provided. The three pixels 532 control the transmittance, reflectance, amount of emitted light, or the like of red light, green light, or blue light. The light colors controlled by the three pixels 532 are not limited to the combination of red, green, and blue, and may be yellow, cyan, and magenta.
A pixel 532 that controls white light may be added to the pixels that control red light, green light, and blue light so that the four pixels 532 collectively serve as one pixel. The addition of the pixel 532 that controls white light can heighten the luminance of the display region. When the number of the pixels 532 functioning as one pixel is increased to use red, green, blue, yellow, cyan, and magenta in appropriate combination, the range of color reproduction can be widened.
