DISPLAY DEVICE

摘要

Provided is a display device, in which an exit light has an angle of view larger in the horizontal direction than in the vertical direction and has such a polarized component in the vertical direction as can be confirmed by polarizing sunglasses, and which can raise a display brightness. A brightness-improved film (33) is extended in the horizontal direction and has a plurality of ridges (33a) arrayed in a direction to intersect that extended direction and having a refractive index made larger in the extended direction than in the arrayed direction. A phase difference plate (34) displaces the polarizing direction of a light incident thereon, in a manner to reduce the angle made between the polarizing direction, in which the polarized component of the light, as having transmitted the brightness improved-film (33), in the arrayed direction of the ridges (33a) and the direction of an polarization axis (a) of a first polarizer (20A). Moreover, a second polarizer (20B) has a polarization axis (b) for transmitting the polarized component of the vertical direction.
