Abstract
A cholesteric liquid crystal display device includes a solar cell, a first substrate, a shielding layer, a first electrode layer, a cholesteric liquid crystal layer, a second electrode layer and a second substrate stacked sequentially from bottom to top. The solar cell includes a metal wiring pattern layer. The shielding layer corresponds to the upper side of the metal wiring pattern layer, and is used to reduce the reflection of light from the metal circuit pattern layer. In this way, the cholesteric liquid crystal display device replaces the traditional black absorbing layer with the black material of the solar cell, which can not only absorb light, but also display the image with self-sustaining power. The cholesteric liquid crystal display device shields the arrangement of the metal wiring pattern layer through the shielding layer, which can ensure the image quality of the display panel.
