Abstract:
A liquid crystal display device including a display unit having a liquid crystal display panel, a flexible circuit board attached to the liquid crystal display panel for applying driving signals to the liquid crystal display panel-, a back light assembly providing light to the display unit, and a mold frame for receiving the liquid crystal display panel and the back light assembly, the flexible circuit board comprising:a flexible base film having a liquid crystal panel engaging portion; a driving IC formed at a central portion of said flexible base film, for applying driving signals to driving devices of the liquid crystal panel; first conductive layer patterns extended on said flexible base film from the driving IC to the liquid crystal panel engaging portion, for electrically connecting the driving IC to the liquid crystal panel, wherein the first conductive layer patterns extend over at least part of the liquid crystal engaging portion of the flexible base film; a solder resin layer partially exposing said first conductive layer patterns formed on the liquid crystal panel engaging portion and covering said first conductive layer patterns near said driving IC; and a reinforcing means for preventing said first conductive layer patterns from disconnecting due to bending fatigue of a border portion of the liquid crystal panel engaging portion and said solder resin layer.
