Abstract
A liquid crystal display device has a flexible circuit board which can prevent the disconnections of output side conductive layer patterns formed at the border portion of the solder resist layer. A flexible base film has a liquid crystal panel engaging portion, engaged with a liquid crystal panel on one side thereof. A driving IC is formed at the central portion of the base film to apply driving signals to driving devices of the liquid crystal panel. A first conductive layer patterns are extended on the base film from the driving IC to the liquid crystal panel engaging portion to electrically connect the driving IC to the liquid crystal panel. A solder resin layer exposes the first conductive layer patterns formed on the liquid crystal panel engaging portion and covers the first conductive layer patterns of the periphery of the driving IC. A reinforcing member prevents the first conductive layer patterns from disconnecting due to the bending fatigue of the border portion of the liquid crystal panel engaging portion and the solder resin layer.
