Planar light source device and display device using the same

摘要

In a planar light guiding device and a display device, plural light guiding rods are arranged in parallel to one another in a housing having an opening portion serving as a light emission face at the upper surface thereof, and a point light source (LED) 2 is disposed so as to oppose to at least one of both the end faces 1 a of each light guiding rod through a space, thereby constituting a light source unit. These light source units are arranged in the metal housing to thereby form the planar light guiding device.
