A display device includes a display panel having a display region, and including a light transmission region overlapping an electronic element within an edge portion of the display region, and a panel driver configured to drive the display panel, and configured to perform an edge-dimming operation that gradually decreases a luminance of an area of the display region excluding the light transmission region from a center portion of the display region to the edge portion of the display region while not decreasing a luminance of the light transmission region.

Display device including a light transmission region, and electronic device

A backlight unit includes a light conversion member; a light guide plate including a light exit surface, a rear surface facing the light exiting surface, and connection surfaces including a first surface and a second surface facing each other to connect the light exit surface and the rear surface; a reflective member; and a light source emitting a first color light incident to the first surface and a portion of the first color light reaches the second surface on which the reflective member is disposed to specularly reflect the portion of the first color light. The light conversion member is disposed on the light exit surface, receives the first color light from the light guide plate, and emits a second color light different from the first color light.
