Abstract

A display device according to this technique includes a slanting surface provided at a lower section of a housing accommodating a display panel and slanted in a depth direction; a receiving light guide member located at the slanting surface and having an incident surface exposed from a front surface of the housing, an emitting surface for emitting light to a light receiving sensor, and a reflective surface provided between the incident surface and the emitting surface; and an emitting light guide member, located at the slanting surface and having a front emitting surface slanted so as to be substantially flush with the slanting surface, for guiding light from a light emitting diode to the front surface of the housing.

Claims (7)

1. A display device comprising:

a slanting surface provided at a lower section of a housing accommodating a display panel and slanted in a depth direction;

a receiving light guide member located at the slanting surface and having an incident surface exposed from a front surface of the housing, an emitting surface for emitting light to a light receiving sensor, and a reflective surface provided between the incident surface and the emitting surface; and

an emitting light guide member, located at the slanting surface and having a front emitting surface slanted so as to be substantially flush with the slanting surface, for guiding light from a light emitting diode to the front surface of the housing.

2. The display device according to claim 1 , wherein the incident surface of the receiving light guide member projects from the slanting surface and is located so as to be substantially parallel to a display surface.

3. The display device according to claim 1 , further comprising an optical unit including a unit main body and a case accommodating the unit main body, the unit main body having a base formed integrally with the receiving light guide member and the emitting light guide member, wherein the optical unit is located at the slanting surface of the lower section of the housing.

4. The display device according to claim 1 , wherein the receiving light guide member comprises a light guide member for guiding infrared light from an infrared remote controller and a light guide member for guiding ambient light.
