ILLUMINATION DEVICE, DISPLAY DEVICE, AND TELEVISION RECEIVING DEVICE

摘要

This backlight device (illumination device) (12) is provided with: a plurality of LEDs (light sources) (17) arranged in a row at intervals; a light-guide plate (16) having a light-receiving surface (16b) that is arranged opposing the LEDs (17) and that receives light from the LEDs (17) and a light-emitting surface (16a) from which the light that entered is emitted; a reflective sheet (reflective member) (20) arranged so as to cover the surface of the light-guide plate (16) opposite to the light-emitting surface (16a) and that reflects light toward the light-emitting surface (16a); and an extended reflective part (26) provided in an edge portion of the reflective sheet (20), the extended reflective part (26) extending toward the LEDs (17) from the light-receiving surface (16b), the extended reflective part (26) having openings (27) formed therein that correspond to the arrangement pattern of the LEDs (17), thereby being arranged corresponding to the non-arrangement pattern where the LEDs (17) are not provided.

主权项

1. An illumination device, comprising:
a plurality of light sources arranged at intervals; a light guide plate having a light-receiving surface facing the light sources to receive light from the light sources and a light-emitting surface through which light that entered the light guide plate is emitted; a reflective member disposed to cover a surface of the light guide plate opposite to the light-emitting surface, the reflective member reflecting light toward the light-emitting surface; and an extended reflective part laterally extending from an edge of the reflective member beyond the light-receiving surface toward the light sources, the extended reflective part having a shape consistent with an arrangement pattern of the light sources such that the extended reflective part is absent below the light sources and is present between the light sources.
