Abstract

A display device is disclosed, which includes a display panel and a backlight module. The backlight module is disposed corresponding to the display panel, and includes a light guide plate, at least one light emitting unit, a reflector and a first pattern. The light guide plate has a central region and an outer region, and the outer region is disposed around the central region. The at least one light emitting unit is disposed adjacent to the light guide plate. At least a part of the reflector is disposed corresponding to a bottom surface of the light guide plate. The first pattern is disposed corresponding to the outer region, and the reflector and the light guide plate are adhered via the first pattern.
