Abstract
A light guide plate includes an incident surface receiving incident light from a light source, an exit section that outputs exit light having a light distribution different from a light distribution of the incident light and a reflective section opposite to the exit section. A plurality of first patterns are formed on the exit section while being arranged in a first direction of the exit section to distribute the exit light with maximum brightness in a direction perpendicular to the exit section. A plurality of second patterns are formed on the reflective section to scatter the incident light.
