摘要： A display device includes: a display panel; a light source; and a light guide plate receiving light from the light source and providing the light to the display panel. The light guide plate includes an upper surface facing the display panel, a light incident surface facing the light source and a light opposing surface opposing the light incident surface. The upper surface includes a lens pattern and the lower surface incudes a prism pattern, the prism pattern includes a plurality of prisms arranged along a first direction from the light incident surface to the light opposing surface, each of the prisms has a length extending in a second direction along a length of the light incident surface, and among the prisms arranged along the first direction within the prism pattern, the lengths of the prisms increase as a distnace from the light incident surface increases.
