Illumination device, display device, and television receiver

Abstract

The backlight unit (49) of a display device (69) having a liquid crystal display panel (59) is provided with a chassis (41), a diffusion plate (43) supported by the chassis, and a light source for irradiating the diffusion plate with light. A reflective sheet (42) for reflecting light towards the diffusion plate is combined with a light-emitting module (MJ), which is a light source. An inclined surface (42a) such that the light emitted from the light-emitting module in the lateral direction is reflected toward the diffusion plate is formed on the peripheral edge of the reflective sheet. The inclined surface is subjected to a reflectance reduction treatment. The reflectance reduction treatment involves forming a plurality of small holes (46A) in the inclined surface, for example.
