Light guide plate, method of manufacturing the same, and liquid crystal display device including the same

A light guide plate comprising:

• a light incident surface to which light is incident as incident light;
• an opposite surface formed opposite to the light incident surface;
• a light emitting surface through which the incident light is emitted;
• a rear surface formed opposite to the light emitting surface and including a prism pattern to reflect the incident light to the light emitting surface;
• and
• lateral surfaces,
• wherein a diffuse reflection pattern is formed on at least any one of the light emitting surface and the lateral surfaces to diffuse-reflect light incident to the lateral surfaces, thus rendering a brightness adjacent both the opposite surface and the light incident surface substantially uniform,
• wherein the rear surface further comprises at least one reflection pattern formed in a prism shape spaced apart from and interposed between prism lines defining the prism pattern to reflect light to the light emitting surface,
• wherein the reflection pattern has a height from the rear surface different from a height of the prism lines defining the prism pattern from the rear surface.
