LIQUID CRYSTAL DISPLAY DEVICE
First Claim
1. A liquid crystal display device comprising a liquid crystal display panel and a backlight,wherein the backlight includes a light guide plate, a mold which accommodates the light guide plate, and a plurality of optical sheets disposed on the light guide plate;
- the mold has an upper surface which faces the liquid crystal display panel;
among the optical sheets, at least the optical sheet that is the closest to the liquid crystal display panel has a part which faces the upper surface of the mold; and
the liquid crystal display panel is bonded to the mold via the part which faces the upper surface of the mold.

Abstract
A liquid crystal display device includes a liquid crystal display panel and a backlight disposed on a back surface of the liquid crystal display panel. A light guide plate, a lower diffusion sheet and a lower prism sheet, are accommodated in a mold. An upper prism sheet extends over an upper surface of the mold, and bonded to the liquid crystal display panel and the mold with an adhesive. An edge of the upper prism sheet as the uppermost layer is invisible even when the screen is viewed from an oblique direction so as to prevent generation of an emission line due to the edge of the optical sheet. A sufficient bonding area is ensured between the mold and the liquid crystal display panel, and separation of the liquid crystal display panel from the mold is prevented under influence of damage.
