Abstract: Disclosed is a lighting device including a light guide plate, a plurality of LEDs, a prism sheet disposed on a side toward the upper surface of the light guide plate, and a reflective sheet disposed on a side toward the lower surface of the light guide plate. The plurality of LEDs are arrayed on a side surface corresponding to a first side of the light guide plate in a first direction along the first side. The prism sheet includes a first prism array that is formed on a surface facing the light guide plate. The first prism array includes prisms that are extended in the first direction and arrayed in a second direction perpendicular to the first direction. The upper surface of the light guide plate and the prism sheet sandwich a diffusion sheet therebetween. The diffusion sheet has a haze value between 30% and 65% when measured in compliance with JIS K7361. The prisms on the first prism array have an apex angle between 55 degrees and 66 degrees.
