Abstract: A solar panel is provided which can be satisfactorily used as an information medium for advertising, announcement, etc. without a decrease in the efficiency of power generation. The solar panel includes a liquid crystal display panel 100 including a memory liquid crystal layer 36 between electrodes, and a solar cell 200. When the solar cell 200 performs power generation, the memory liquid crystal layer 36 is changed to an optically transparent state. On the other hand, when the solar cell 200 does not perform power generation, pixels in a light scattering state are formed in a predetermined portion of the memory liquid crystal layer 36, thereby performing light display, and pixels in an optically transparent state are formed in the other portion of the memory liquid crystal layer 36, thereby performing dark display, whereby an image including a combination of the light display and the dark display is formed on the liquid crystal display panel 100.
