摘要： A backlight unit capable of reducing or effectively preventing a hot spot phenomenon includes a plurality of light sources generating lights, a light guide plate including a portion on which the lights generated from the light sources are incident and converting the lights incident on the portion into a surface-shaped lights and a light path converter converting a traveling direction of the lights incident on the portion of the light guide plate in an area where the lights emitted from the light sources diodes, overlap each other.

摘要翻译： 能够减少或有效地防止热斑现象的背光单元包括产生光的多个光源，包括从光源产生的光入射的部分的导光板，并将入射到该部分上的光转换为 在从光源二极管发出的光的区域中，入射在导光板的部分上的光的行进方向相互重叠的光路转换器。
