Abstract

A liquid crystal display device includes a liquid crystal panel including a pad electrode, a tape circuit substrate and an anisotropic conductive film. The pad electrode receives one of a driving signal and a power supply voltage signal. The tape circuit substrate includes a base film made of an insulating material, and a signal line formed on the base film and having a slit at a portion of the signal line which overlaps the pad electrode of the liquid crystal panel. The anisotropic conductive film connects the outer lead with the pad electrode.
