Abstract: Disclosed is a display device, comprising: two liquid crystal cells connected together and facing in opposite directions, each liquid crystal cell includes a substrate, a pixel electrode, a common electrode, and a cholesteric liquid crystal layer filled between the pixel electrode and the common electrode, the polarization properties of the filled cholesteric liquid crystals are opposite to each other. In the present invention, the two cholesteric liquid crystal cells are connected together, such that transparent display as well as double-side display can be achieved by using the reflective, polarizing and full stable performance of the cholesteric liquid crystals as well as by controlling voltage to switch two cholesteric liquid crystal cells between a plane orientation and a vertical orientation. In addition, with this technology, no polarizer is used and light absorption is removed, thus, the transmission rate of the display device is improved. Further, with this technology, no backlight is required, and the display is achieved by using the reflection-transmission of the cholesteric liquid crystals, therefore, energy is saved. Moreover, with this technology, no liquid-crystal-molecule alignment film is required and no rubbing process is required, therefore, the process is simplified.
