WIPO Patent Application WO/2012/118316
Kind Code:
A3
Abstract:
The present invention relates to an edge-type lighting device in which a light source is not pushed when a light guide plate is thermally expanded. In the lighting device according to the present invention, a light guide plate (2) is slidably supported so that the light guide plate (2) is expandable in the planar direction, and a light source (3) disposed on one side of the light guide plate (2) is movably supported in the same direction as well. A light guide plate stopper (4b) is disposed at a position facing an edge (2A) of the light guide plate (2) to prevent the light guide plate (2) from expanding excessively. Thus, the light source (3) may be prevented from being pushed toward a frame member (4).
