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 an aspect, a display device includes a plurality of pixels. Each pixel includes two sub-pixels adjacent to each other in a first direction. Each sub-pixel has one of three colors allocated thereto. Two colors of the two sub-pixels included in the pixel are different. The two colors of the two sub-pixels and a positional relation between the two sub-pixels are the same in each of the pixels arrayed in a second direction. One color not allocated to the two sub-pixels included in a first pixel out of the three colors is allocated to at least one of the sub-pixels included in second pixels adjacent to the first pixel in the first direction. The sub-pixels having the same color allocated thereto are arranged along the first direction with one sub-pixel interposed therebetween, the one sub-pixel having another color allocated thereto.
