Abstract: According to one embodiment, a display device displays a color gamut defined by connecting a first defined color in first chromaticity coordinates, a second defined color in second chromaticity coordinates, and a third defined color in third chromaticity coordinates. An illumination device of the display device includes green, blue and red lasers. The green and blue lasers emit light of the second and third defined colors, and red laser emits light of a color in fourth chromaticity coordinates. Each of the pixels displays a color including the first defined color by mixing light in the fourth chromaticity coordinates and the second defined color.

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 backlight unit includes a light source, a first lens, a second lens, and a light guide unit. The light source emits light which is diffused as the light travels in a first-A direction, the light being diffused in a second direction intersecting the first-A direction, and a third direction intersecting the first-A direction and the second direction. The first lens and the second lens are arranged in an optical path of the light. The first and second lenses control the light such that the first lens controls a beam width of the light in the second direction, and the second lens controls a beam width of the light in the third direction, thereby converting the light into parallel light.
