Abstract:
1. A display device comprising: a light guide plate comprising an upper surface, a lower surface facing the upper surface, a plurality of side surfaces connecting the upper surface and the lower surface, and a cross-sectional surface having a plurality of light incident surfaces and a plurality of connecting surfaces connecting adjacent light incident surfaces; a display panel assembly comprising a display panel disposed on the upper surface, and a driving substrate configured to drive the display panel; and a light source unit comprising a first substrate having surfaces opposite each of the cross-sectional surfaces, wherein the plurality of light incident surfaces have different light emitting angle with respect to one of the plurality of side surfaces, wherein all of the different light emitting angles are acute angles with respect to one of the plurality of side surfaces, and wherein the light incident surfaces are substantially perpendicular to light emitting directions and the light emitting directions do not intersect each other within the light guide plate.
