Abstract:
A light guide plate includes: a plate surrounded by two main surfaces and a plurality of end surfaces connecting the main surfaces, one of the end surfaces designated as an entrance surface, one of the main surfaces designated as a reflection surface; a first reflection element provided in a first region of the reflection surface separated from the entrance surface, and configured to reflect a light incident from the entrance surface in a first angle with respect to the reflection surface; and a second reflection element provided in a second region of the reflection surface between the entrance surface and the first region, and configured to reflect the light in a second angle different from the first angle with respect to the reflection surface.
