Abstract
Color cholesteric liquid crystal display devices and fabrication methods thereof are provided. The color cholesteric liquid crystal display device includes a first substrate, a second substrate and a gap interposed therebetween. A patterned enclosed structure is interposed between the first substrate and the second substrate dividing a plurality of color sub-pixel channels. A plurality of color cholesteric liquid crystals are respectively filled in each of the color sub-pixel channel, wherein an adhesion layer is tightly adhered between the second substrate and the patterned enclosed structure so as to prevent mixing of the color cholesteric liquid crystals between adjacent color sub-pixel channels.
