Abstract

Official abstract text for this publication.

In a liquid crystal display device including a backlight unit that irradiates the entire image formation region with light from light emitting diodes disposed in a concentrated manner, in order to reduce warpage of a reflection sheet to obtain uniform illumination, provided is a liquid crystal display device ( 1 ), including: a liquid crystal panel ( 3 ); a reflection sheet ( 6 ), which is disposed on a rear surface side of the liquid crystal panel ( 3 ) and is curved so as to have a concave surface facing the liquid crystal panel ( 3 ); a light emitting diode substrate on which a plurality of light emitting diodes ( 14 ) are disposed along a horizontal direction; and a support ( 21 ) for fixing the reflection sheet ( 6 ) at a curved portion of the reflection sheet ( 6 ).

First claim

Opening claim text (preview).

What is claimed is: 1. A liquid crystal display device, comprising: a liquid crystal panel; a reflection sheet, which is disposed on a rear surface side of the liquid crystal panel and, as viewed in vertical cross section, comprises a flat portion and curved portions extending from a periphery of the flat portion toward the liquid crystal panel so as to define a single concave surface facing the liquid crystal panel, a periphery of the concave surface substantially corresponding…
