摘要： A light-emitting module includes a light guide plate and a light source unit in accordance with an embodiment. The light guide plate include 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 connected to at least one of the side surfaces. The light source unit includes a substrate disposed in correspondence with the cross-sectional surface and a point light source mounted on the substrate to emit light to the cross-sectional surface. Thus, light-emitting efficiency may be enhanced and the arrangement of point light sources may be optimized, so that a required amount of emitted light may be obtained using a small number of the point light sources. In addition, uniformity of luminance and heat-radiating efficiency may also be enhanced.
