Illuminating device, display device, and television receiving device

摘要

Provided is an illuminating device capable of uniformalizing intensity distribution in a plane of light that is emitted to the outside even when a light source includes a non-emitting portion or a low reflective portion. The illuminating device includes a light source including a plurality of light-emitting elements, and a light guide member including an entrance face opposing the light source, from which light emitted from the light source enters the inside of the light guide member, wherein the light source includes a non-emitting portion where the light-emitting elements are not disposed, and wherein light projected from a portion of the light source, the portion being close to the non-emitting portion, onto the entrance face of the light guide member is higher in intensity than light projected from the other portion of the light source onto the entrance face of the light guide member.

主权项

1. An illuminating device, comprising:
a light source comprising:
a board; anda plurality of light-emitting elements mounted on the board; and a light guide member including an entrance surface opposing the light source, from which light emitted from the light source enters the inside of the light guide member; wherein the light source includes a non-emitting portion where the light-emitting elements are not disposed; light projected from a portion of the light source, the portion being close to the non-emitting portion, onto the entrance surface of the light guide member is higher in intensity than light projected from an other portion of the light source onto the entrance surface of the light guide member; and a space between the light-emitting elements on the portion close to the non-emitting portion is smaller than a space between the light-emitting elements on the other portion.
