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 has a plurality of convex sections 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 changes the polarization direction of light entering the wave plate so that an angle made by a polarization direction of the polarization component in the arrangement direction of the convex section after passing through the wave plate among light passing through the luminance enhancement film and the direction of a polarizing axis a of a first polarizer becomes small. A second polarizer has a polarizing axis b that transmits the polarization component in the vertical direction.
