Abstract: In the case of a pixel including four and more sub pixels, the area of one pixel is larger than that in the case of a pixel including three sub pixels; therefore, high definition becomes difficult. When a central display area has a structure of four and more sub pixels, in a display device, the pixel structure in a peripheral display area for use in creating a virtual image is reduced to three sub pixels, to allocate the vacant space for high density assignment. Only the pixel density in the vicinity of a frame of a lens portion is compressed, in order to apparently resolve the discord with the image of a non-lens portion. The pixel side in the peripheral display area may be even or gradually narrowed.
