Problems solved by technology

[0022] Although these gaps between parts can prevent wrinkles in the optical sheet pack when the optical sheet pack is assembled, they cannot prevent noise caused by the movement of the optical sheet pack when the LCD device is shaken by hand
[0023] Therefore, the optical sheet group used in the liquid crystal display device according to the related art has structural limitations in preventing noise due to movement of the optical sheet group when the liquid crystal display device is shaken by hand.

Abstract

Described is a liquid crystal display device including an edge light source array or a direct-type light source array and a group of optical sheets disposed over a light guide plate. The liquid crystal display device has at least one foot that extends towards the side of the bottom cover from one edge of a top sheet among the group of optical sheets. The at least one foot partially fixes the group of optical sheets to prevent movement in the vertical and horizontal directions in an upright display orientation, while allowing for expansion of the optical sheets during manufacturing.

Description

technical field [0001] The present invention relates to a liquid crystal display device, and more particularly, to a liquid crystal display device in which movement of an optical sheet can be suppressed by changing the structure of the sheet. Background technique [0002] Today, image displays have changed from cathode ray tubes to liquid crystal displays, plasma display panels, and the like. In particular, liquid crystal displays have attracted great attention as next-generation image displays because they have lower power consumption, are thinner and lighter than cathode ray tubes, and emit less unwanted Electromagnetic radiation. [0003] A liquid crystal display device includes a lower substrate having TFTs (thin film transistors), an upper substrate on which color filters are disposed, and a liquid crystal layer injected between the lower substrate and the upper substrate. [0004] TFTs on the lower substrate are used to transmit and control electrical signals, and li...
