Abstract

A liquid crystal display device includes a liquid crystal cell, a light source, a light guide plate, a first flexible printed cable and a second flexible printed cable. The light source emits light. The light guide plate guides the light to illuminate the liquid crystal cell. The first flexible printed cable is electrically coupled to the liquid crystal cell. The second flexible printed cable is electrically coupled between the light source and the first flexible printed cable. The second flexible printed cable has a printed circuit, a first insulating film formed on one side of the printed circuit and a second insulating film formed on the other side of the printed circuit. The printed circuit is partially exposed on the one side of the printed circuit to form a first land that is electrically coupled to the light source and a second land that is electrically coupled to the first flexible printed cable.
