Light source device and display

摘要

A light source device includes: a light guide plate having a first internal reflection plane and a second internal reflection plane which face each other; one or more light sources each applying illumination light through a side surface of the light guide plate into an interior thereof; and an optical device disposed to face the light guide plate, and modulating, for each of partial regions thereof, a state of light rays exiting therefrom. One or both of the first and the second internal reflection planes each have scattering regions each allowing the illumination light from the light sources to be scattered and exit from the first internal reflection plane of the light guide plate, and one or both of the first and second internal reflection planes each have total-reflection regions allowing the illumination light from the light sources to be reflected in a manner of total-internal-reflection.

主权项

1. A display device comprising a display section and a light source device, the light source device including:
a light guide plate having a first plane and a second plane which face each other; one or more light sources each disposed beside the light guide plate along a side surface thereof; and an optical device disposed to face the second plane, wherein the display section is disposed to face the first plane, one or both of the first plane and the second plane of the light guide plate each have regions each allowing a part of light from the light sources to exit from the light guide plate, and at least a part of the optical device corresponding to a region of the display section performing a three-dimensional display is controlled to stay in a light-off state.
