• a first substrate;
• a circular polarizer on the first substrate;
• a cholesteric liquid crystal (CLC) color filter on the circular polarizer;
• a first electrode on the cholesteric liquid crystal (CLC) color filter;
• a second substrate spaced apart from the first substrate;
• a linear polarizer beneath the second substrate;
• a retardation layer beneath the linear polarizer;
• a second electrode beneath the retardation layer;
• a liquid crystal layer between the first and second electrodes;
• a back light under the first substrate;
• and
• a diffusive film on the second substrate.

A manufacturing method of a cholesteric liquid crystal (CLC) display device, comprising:

• forming a circular polarizer on a first substrate;
• forming a cholesteric liquid crystal (CLC) color filter on the circular polarizer;
• forming a first electrode on the cholesteric liquid crystal (CLC) color filter;
