Abstract: According to one embodiment, in the display device, on the substrate opposed the liquid crystal panel, an element is formed by grooves having steps in a minute and periodic pattern, and the element separates the backlight from the light source unit into light of different color wavelengths and diffract them toward the corresponding color subpixels of the liquid crystal panel. In the light source unit, the first lens shapes the incident light from the light source according to the shape of the display surface of the panel, and the second lens irradiates the light incident surface of the substrate with the light shaped by the first lens as the backlight.

Abstract: According to one embodiment, a display device includes a first arrangement layer and a second arrangement layer. The first layer includes a first pixel, a second pixel, and a third pixel are arranged periodically in one direction. The second layer is opposed to the first layer, and the second layer includes a first element, a second element, and a third element which are arranged periodically to correspond to the first pixel, the second pixel, and the third pixel, respectively, and separate emission light to light of wavelength corresponding to a first color, light of wavelength corresponding to a second color, and light of wavelength corresponding to a third color to be emitted on the first pixel, the second pixel, and the third pixel, respectively.
