摘要： Provided is an illumination device capable of preventing a reflection sheet in the periphery of a light-emitting element from being raised while minimizing the instability in the fixture of a diffusion lens. The illumination device comprises a light-emitting element, a mounting substrate, a diffusion lens, and a reflection sheet having a through-hole. The diffusing lens includes a lens portion for diffusing light, and a fixed portion to be fixed to the mounting substrate. An engaging portion that sandwiches the reflection sheet between the engaging portion and the mounting substrate is formed in the fixed portion.

摘要： The present invention makes it possible to (i) obtain a sufficient and uniform luminance on an entire surface, which is irradiated with light, of a light guide plate and (ii) achieve a reduction in cost. LED light source substrates (140a) and (140b ) are each configured to emit light having a first luminance gradient on an edge of a range, to be irradiated with light, which first luminance gradient is smaller than a second luminance gradient of light having a substantially uniform luminance on an entire range to be irradiated with light.
