Abstract: A curved liquid crystal display device includes a liquid crystal display panel, a backlight unit, a bottom cover and a reinforcement frame. The liquid crystal display panel includes a thin film transistor substrate and a color filter substrate. The backlight unit applies light to the liquid crystal display panel. The bottom cover supports the backlight unit and has a flat shape. The reinforcement frame has a predetermined curvature and is attached to the bottom cover. The flat bottom cover is mounted on the reinforcement frame such that the flat bottom cover has the predetermined curvature of the reinforcement frame.

Abstract: A display device includes a display panel and a back cover coupled and fixed to each other via a resin layer to manufacture a lightweight, thin display device having a slim bezel while increasing the drooping resistance of the display device. In addition, since the drooping resistance of the display device is increased, it is possible to reduce the thickness of the back cover, whereby it is possible to further reduce the weight of the display device. Furthermore, a through-hole is formed in a cover shield such that a portion of the upper part of an IC chip of a substrate can be inserted into the through-hole, with the result that the coupling structure of a circuit unit is improved, whereby it is possible to further reduce the thickness of the display device.
