Patent ID: 8534859

Claim:
A liquid crystal display device, comprising: a liquid crystal panel having a display region at which an image is displayed; and a backlight unit disposed below the liquid crystal panel, wherein: the backlight unit comprises: at least one mounting substrate on which a plurality of light emitting diodes are mounted; a radiator plate; and a reflection member; the reflection member has a reflection surface which is formed to have a recess surface shape below the liquid crystal panel; the plurality of light emitting diodes on the at least one mounting substrate are disposed on a bottom portion of the reflection surface which is formed to have the recess surface shape; the at least one mounting substrate is disposed at a position on an outer side of the reflection surface in the recess surface shape and under the bottom portion; the at least one mounting substrate comprises a plurality of mounting substrates; any two mounting substrates of the plurality of mounting substrates are disposed with an interval provided therebetween; the radiator plate has a hollow through hole formed between the any two mounting substrates disposed with the interval provided therebetween; the radiator plate is disposed under the at least one mounting substrate; and the radiator plate has, in plan view, a larger area than the at least one mounting substrate and a smaller area than the display region of the liquid crystal panel.
