摘要: A backlight unit adapted to implement enhanced light efficiency and uniform brightness is disclosed. The backlight unit includes a plurality of light sources arranged at fixed intervals, a diffusion plate disposed on the plurality of light sources, prism patterns formed on one surface of the diffusion plate, and micro-lens patterns formed on the other surface of the diffusion plate. The vertex angle of each prism pattern is in a range of about 64°˜76°.
