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.
