| titleOfInvention | Planar light source device and display device using the same |
| abstract | In a planar light source device, light from a point light source is reflected by a side surface of a light guide plate, and the light is not spread evenly, resulting in uneven brightness, and is emitted from the light guide plate and reflected by the reflector plate. Therefore, there was a problem that the light use efficiency was low. According to a planar light source device according to the present invention, a light guide plate having a flat plate shape having a rectangular shape in plan view is provided, and the light guide plate is opposite to a light exit surface facing the opening. A pair of side surfaces 13b and a point light source 16 having a hole 13c opening on the opposite side of the first emission side surface and in the vicinity of the first side surface, and disposed in the hole 13c. Is a prism that has a ridge line in a direction perpendicular to the surface, and a cross-section in a direction parallel to the light exit surface, which is formed into a concave and convex shape with a saw shape, so that the light from the point light source is efficiently uniformized on the light guide plate And uneven brightness can be prevented.
