DISPLAY DEVICE

摘要

A display unit in which the view angle in the horizontal direction of emitting light is wider than the view angle in the vertical direction thereof, in which the emitting light has a polarization component in the vertical direction viewable with the use of a polarized sunglass, and which is able to improve display luminance is provided. A luminance enhancement film 33 has a plurality of convex sections 33a which extend toward in the horizontal direction and are arranged in the direction crossing the extending direction, and in which the refractive index in the extending direction is larger than the refractive index in the arrangement direction. A wave plate 34 changes the polarization direction of light entering the wave plate 34 so that an angle made by a polarization direction of the polarization component in the arrangement direction of the convex section 33a after passing through the wave plate 34 among light passing through the luminance enhancement film 33 and the direction of a polarizing axis a of a first polarizer 20A becomes small. A second polarizer 20B has a polarizing axis b that transmits the polarization component in the vertical direction.
