Abstract
A partial polarization member is provided on a second substrate. The partial polarization member is provided corresponding to an aperture of a reflection film, and is not provided in other areas that overlap with reflectors of a reflection film. Therefore, light that is incident from a backlight is reflected by the reflection film and returns to the backlight, without generating loss due to absorption or the like. The light that returns to the backlight is reflected by a backlight reflection film of the backlight, and is output to the aperture of the reflection film.
