Light guide elements for display device
摘要:
A light guide element includes a light-emitting section including a light-emitting surface, a light guide section, and a diffusing device provided in at least part of a region extending from a boundary surface between the light-emitting section and the light guide section, to point halfway between the boundary surface and an end of the light guide section closer to the light source. The light guide element might be used to form a backlight for a liquid crystal display device.
