Abstract: A display apparatus includes a backlight assembly, a first display panel assembly and a second display panel assembly. The backlight assembly includes a plurality of lamps disposed substantially parallel with each other. The backlight assembly emits first light through a first face and second light through a second face. The first display panel assembly is disposed adjacent to the first face to receive the first light. The second display panel assembly is disposed adjacent to the second face to receive the second light. The backlight assembly may further include a driving inverter electrically connected to first and second ends of the lamps to provide the lamps with driving voltages. Therefore, the backlight assembly applies light to the first and second display panel assemblies to reduce the number of backlight assemblies. Therefore, costs for manufacturing a display apparatus may be reduced.

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.
