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.

Abstract: A liquid crystal display device includes a liquid crystal between a TFT substrate including pixels formed in a matrix, and a counter substrate. A pixel electrode is formed in an area surrounded by scanning lines and video signal lines. A common electrode is formed in a lower layer of the pixel electrode through an interlayer insulating film. A long side of the pixel electrode of a first pixel is inclined at a first angle clockwise at a right angle to the extending direction of the scanning line. A long side of the pixel electrode of a second pixel is inclined at the first angle counterclockwise at a right angle to the extending direction of the scanning line. The liquid crystal is a negative type liquid crystal. Further, a protrusion formed in the long side of the pixel electrode has a side parallel to the extending direction of the scanning line.
