    摘要： In a light guide plate and a backlight unit, a light guide plate includes a light incident surface, an opposite surface, a top surface, a bottom surface, and a plurality of optical path changing units. The optical path changing units are aligned on at least the bottom surface of the top surface and the bottom surface at a predetermined interval while protruding in parallel to a reference line perpendicular to the light incident surface. Accordingly, power consumption used to generate the light may be reduced.

    摘要翻译： 在导光板和背光单元中，导光板包括光入射表面，相对表面，顶表面，底表面和多个光路改变单元。 光路改变单元至少在顶表面和底表面的底表面上以预定间隔对准，同时平行于垂直于光入射表面的参考线突出。 因此，可以减少用于产生光的功率消耗。

    摘要： An optical member includes; an incident surface on which light is incident, an exit surface which is disposed substantially opposite the incident surface and from which the light exits, a prism pattern disposed on the exit surface, and a diffusion pattern which is aligned with the prism pattern and is disposed in a total internal reflection region in which the light incident on the incident surface is totally internally reflected by the prism pattern and output through the incident surface.
