Abstract: A light source module including a light guide plate, at least one light emitting device, a light-controlling pattern element, and an absorbing pattern element is provided. The light guide plate has a light emitting surface, a first surface opposite the light emitting surface, and at least one opening. The opening passes through the first surface and extends from the first surface toward the light emitting surface. The at least one light emitting device is disposed in the opening and arranged along an arranging direction. The light-controlling pattern element is disposed on the light emitting surface and covers the opening and the light emitting device. The opening faces towards the absorbing pattern element. The absorbing pattern element is disposed besides one of the at least one light emitting device and extends toward a side wall of the opening. Moreover, another two light source modules are also provided.

Abstract: A display device includes a light guide plate, at least one illuminating element, a side frame, and a display panel. The light guide plate includes a main body and at least one light-incident protrusion part. The main body has a light-emitting surface. The light-incident protrusion part is connected to the main body and has a light-incident surface. The illuminating element is arranged along the light-incident surface and is capable of emitting a light beam. The light beam enters the light guide plate from the light-incident surface and leaves the light guide plate from the light-emitting surface. The side frame is located on the light guide plate. The display panel is located between the light guide plate and the side frame. The side frame and the display panel expose the light-incident protrusion part. The side frame of the display device described herein has the small width.
