<p>PURPOSE: A backlight unit is provided to improve a photonic efficiency by maintaining separation distance between a light emitting element and a light guiding plate as an optimized distance. CONSTITUTION: A backlight unit includes a bottom chassis(110), a light guiding plate unit, a substrate, a fixing member(140), and a sliding moving unit(160). The light guiding plate is accepted to the bottom chassis. The substrate has a light emitting element which examines the light to the light guiding plate. A fixing unit member fixed the substrate and the light guiding plate by being arranged in the bottom chassis. The sliding moving unit fixes the fixing member to be movable about the bottom chassis.</p> |
