Problems solved by technology

[0005] However, in the flat-panel lighting device according to Japanese Patent Laid-Open No. 2003-031016, the linear light guide must have an uneven surface opposite to the light exit surface in order to adjust the progress of light incident from the side surface of the linear light guide. The direction is changed to a direction perpendicular to the light exit surface of the side surface, and thus, there is a disadvantage that the shape of the linear light guide (light guide plate) is complicated

Abstract

The invention discloses a display device and a television set. This display device includes a display device body, a display portion arranged on the front side of the display device body, configured to display an image, a light source supplying light to the display portion, a first light guide plate arranged to be opposed to the light source, having a light incident surface including a side surface on which light emitted from the light source is incident and a light emitting surface provided on a side surface opposite to the light incident surface to emit the light incident from the light incident surface, a second light guide plate arranged to overlap with the first light guide plate, guiding the light emitted from the light emitting surface of the first light guide plate to the display portion, and a first reflective member arranged between the first light guide plate and the second light guide plate. Unevenness in brightness on a display portion is suppressed while suppressing complication of the shape of a light guide plate and an increase in the width of a frame even when the number of light sources is reduced.

Description

technical field [0001] The present invention relates to a display device and a television, and more particularly, to a display device and a television each including a light source and a light guide plate. Background technique [0002] As is well known, a display device includes a light source and a light guide plate, as disclosed in Japanese Patent Laid-Open No. 2003-031016. [0003] Japanese Patent Laid-Open No. 2003-031016 discloses a flat lighting device (display device), including: a flat lighting device main body (display device main body); an illumination object (display part), arranged in front of the flat lighting device main body a side configured to display an image; and a point light source (light source) providing light to an illumination object. This flat panel lighting device includes: a linear light guide body having a side surface (light incident surface) and a light exit surface on which a plurality of point light sources are arranged and on which light em...
