Backlight device, light source device, lens, electronic apparatus and light guide plate

摘要

Disclosed herein is a backlight device. The device includes: a light emitting element; a lens having an incident surface on which light emitted by the light emitting element is incident, and an outgoing surface which has an ability to converge the light and from which the light incident on the incident surface goes out; a light guide plate having a light incidence plane and introducing through the incidence plane the light going out from the outgoing surface, so as to perform surface light emission; and a reflective member operative to reflect a portion of the light going out from the outgoing surface of the lens, toward the incidence plane of the light guide plate.

主权项

1. An apparatus comprising:
a lens including
an incident surface configured to receive light emitted by a light emitting element;a side surface including a portion arranged to extend parallel to a base part of a reflective member; andan outgoing surface configured to converge light so that a portion of light incident on the incident surface is transmitted toward a wedge part of the reflective member; and the reflective member including
the base part having a constant thickness; andthe wedge part integrally formed with the base part, the wedge part extending from the base part and being tapered away from the outgoing surface of the lens beginning at a junction of the side surface and the outgoing surface of the lens.
