Abstract: In one embodiment, a display device includes first and second substrates, a liquid crystal layer, a polarizing element, a light source, and a bending member. The first substrate includes first and second surfaces and a side surface. The second substrate includes third and fourth surfaces. The polarizing element is provided on the fourth surface side of the second substrate. The light source irradiates the side surface with polarized parallel light. The bending member bends a path of the light entering the first substrate from the light source such that the light goes to the second substrate. No polarizing element is provided between the first substrate and the light source, and the bending member is provided on the second surface side of the first substrate.

Abstract: In a color display device, when using white (W) sub-pixels in addition to subpixels of red (R) and green (G) plus blue (B) without increasing a wiring line number, the per-color pixel number in a unit area decreases so that the image resolution is deteriorated. The area and number of subpixels are adjusted in accordance with the visual sensitivity or luminosity required. Practically, the area of red (R) and blue (B) subpixels which are relatively low in luminosity is set to be about two times greater than the area of green (G) and white (W) subpixels that are relatively high in luminosity while letting the number of green (G) and white (W) subpixels be twice the number of red (R) and blue (B) subpixels. A larger subpixel is configured from a plurality of unit subpixels. A smaller subpixel is formed of a one unit subpixel.
