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.

Abstract: According to one embodiment, a display device includes a light source unit, a light guide unit, a lens, and a light emitting layer. The light source unit emits light to the light guide unit. The lens concentrates the light emitted from the light source unit. The light guide unit guides the light concentrated by the lens toward the light emitting layer. The light guided by the light guide unit is transmitted to the light emission layer without any intervening prism layer.
