LIGHT EMITTING DEVICE

摘要

PURPOSE: A light emitting device is provided to form exit surface of the light guiding plates, thereby preventing female unit to be formed on both end part of an exit surface and unifying the luminance of light photographed to the light guiding plates. CONSTITUTION: A printed circuit board(112) is expanded to a first direction. A plurality of emitting light device(114) generates light, which is amounted along the first direction on one side of the printed circuit board. A lower surface is faced with photographed surface of each light guiding plate. The surface of a photographed surface includes a plurality of concave parts formed concavely to an inner direction of light guiding plate.
