1. A cholesteric liquid crystal display comprising a first selective light reflection module for reflecting a first light, a second selective light reflection module for reflecting a second light, and a third selective light reflection module for reflecting a third light, which sequentially stacked from bottom to top, the incident light going into said cholesteric liquid crystal display from the top of said third selective light reflection module, wherein:
the wavelength ranges of said first light, said second light, and said third light are different;
said cholesteric liquid crystal display further comprises a first thin-film photovoltaic module disposed between said third selective light reflection module and said second selective light reflection module, and a second thin-film photovoltaic module disposed between said second selective light reflection module and said first selective light reflection module;
wherein said first thin-film photovoltaic module is partially photo-permeable in which the transmittance of said third light is lower than the transmittance of the other lights;
wherein said second thin-film photovoltaic module is partially photo-permeable in which the transmittance of said second light is lower than the transmittance of the other lights.
