A color cholesteric liquid crystal display device includes a color cholesteric liquid crystal display panel with a plurality of sub-pixels. A driving module exerts a first voltage on a portion of sub-pixels of the color cholesteric liquid crystal display panel to hold displaying states of the biased sub-pixels. An input element exerts pressure on the color cholesteric liquid crystal display panel to change displaying states of the unbiased sub-pixels.
