SURFACE LIGHT SOURCE AND METHOD FOR MANUFACTURING THEROF AND LIQUID CRYSTAL DISPLAY DEVICE USING THE SAME

摘要

A surface light source device, a method for manufacturing the same, and a liquid crystal display using the same are provided to extend the lifespan of the device by preventing a decrease of discharge gas through the use of protective films and a light reflector layer. A surface light source device comprises a light source body, a space divider wall(300), and a power apply unit(400). The light source body has space formed therein, and includes a protective film(240) for preventing a decrease of discharge gas and a fluorescent layer(260) formed on the protective film so as to change the non-visible light generated by the discharge gas into visible light. The space divider wall divides the space of the light source body into two discharge spaces. The power apply unit applies a discharge voltage to the discharge gas so as to generate the non-visible light from the discharge gas.
