Abstract
A liquid crystal display device includes a liquid crystal display panel and a backlight. The backlight includes: a light emitting diode substrate on which light emitting diodes are mounted; a reflection sheet that is provided on the light emitting diode substrate and has holes formed therein, each of the light emitting diodes being provided inside each of the holes; and lenses provided on the light emitting diodes, for diffusing light from the light emitting diodes. Each of the lenses is larger than the each of the holes, and entirely covers the each of the holes and also covers a part of the reflection sheet including an entire periphery of the each of the holes.
