Abstract
A cholesteric liquid crystal composite display device includes a cholesteric liquid crystal reflective display device and a transmissive display device. The transmissive display device is located below the cholesteric liquid crystal reflective display device. When the cholesteric liquid crystal reflective display device is displayed in a transparent state, the light transmittance of the cholesteric liquid crystal reflective display device is higher than that of the cholesteric liquid crystal reflective display device when it is displayed in a dark state through a rated driving mode. Thereby, the display of the cholesteric liquid crystal composite display device is made clearer and the display quality is improved.
