A power supply system generates supply electric power by using a power generation fuel. The system includes a fuel charged portion in which the power generation fuel is charged, a power generator which generates power generation electric power by using the power generation fuel, an output controller which operates or stops the power generator and, a start-up controller which supplies start-up electric power used for operating the output controller to the output controller.

Power supply system and device driven by power supply system

In a liquid crystal display device using color filters, the area of each of color filters arranged on the inner surface of one of substrates in correspondence with the pixel areas is set to be smaller than that of each pixel area to form non-colored light exit areas, and color pixels are displayed with non-colored light which is not transmitted through the color filters and colored light which is transmitted through the color filters. Since high-luminance color pixels are displayed with these colored light and non-colored light, the screen can be made brighter. The liquid crystal display device further includes a reflecting member for reflecting external light incident from the front side of the device and transmitted through the liquid crystal layer toward the front side. In addition, in the liquid crystal display device, reflecting films for reflecting light incident from the front side of the device toward the front side are arranged on the inner surface of the front-side substrate in correspondence with the areas between the respective pixel areas, thereby making the portions between the respective pixel areas bright and further increasing the overall brightness of the screen.
