Liquid crystal display device with reduced frame portion surrounding display area

摘要

A liquid crystal display device. The liquid crystal display device has a peripheral circuit including a liquid crystal display having drive ICs COG-packaged on a transparent substrate, and a foldable multi-layered flexible substrate having two or more conductor layers, so that the compact packaging can be realized to reduce EMI noise and the number of parts. The liquid crystal display device may also include a display controller having two or more display control integrated circuit elements packaged therein, and drive ICs mounted by a chip-on-glass packaging on two sides of a liquid crystal display panel, usually, on the longer sides, so that the display controller excellent in the temperature resistance and advantageous in compact and a video signal line driving circuit board are uniformly arranged at the upper and lower sides of a screen. As a result, the vertical positioning of the screen can be made proper to take an advantage in the compact packaging. Further, the liquid crystal display device may have a peripheral circuit board positioned in an outer periphery of a seal port recessed to avoid the projection of the seal port and in which a fluorescent tube has its two lamp cables arranged around four sides of a liquid crystal display element, so that the substrate at the seal port side and the lamp cable of a side light type back light can be compactly packaged.
