Abstract

The present invention provides a display device which allows reducing luminance unevenness around a non-display region even in a case where the non-display region is provided in a given position. A liquid crystal display device includes: a liquid crystal panel; a front polarizer and a back polarizer each having a polarizer opening; and a backlight unit having a unit opening. The backlight unit includes: a light guide plate; a light source provided on an end surface of the light guide plate; and edge parts respectively surrounding (i) an outer periphery of the backlight unit and (ii) the unit opening. A reflection member is provided on a portion of an outer peripheral surface of the edge part surrounding the unit opening which portion is on a side opposite to the light source, the reflection member reflecting scattered light which has been scattered by the edge part.
