  • Patent number: 7405797
    Abstract: A lamp lighting terminal which is a conductive pad connected to a power supply terminal of a lamp is mounted on a surface opposite to a light emitting surface of a flat light source apparatus. Then, a terminal of a inspection device is brought into contact with the lamp lighting terminal to light up a liquid crystal display apparatus, thereby allowing inspection to be carried out. The flat light source apparatus may be provided with a light guide inputting lights from a light source through the side to output the light through one surface. In this configuration, inspection work at the time of lighting inspection of a liquid crystal display is simplified, and a high-quality liquid crystal display can be obtained.
