Patent ID: 7864285

Claim:
A color cholesteric liquid crystal display device, comprising: a first substrate, a second substrate opposed to each other with a gap therebetween; a patterned enclosed structure interposed between the first substrate and the second substrate dividing a plurality of color sub-pixel channels; and a plurality of color cholesteric liquid crystals respectively filled in each of the color sub-pixel channels; 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, and wherein the patterned enclosed structure comprises a unitary structure having a plurality of stripe wall structures, a straight seal line connected to and perpendicular to the same end of each stripe wall structure, and a solid bulk region with a relative larger width than the stripe wall structures connected to the other end of each stripe wall structure, wherein the unitary structure defines three different length liquid crystal channels, and wherein the unitary structure of the plurality of stripe wall structures, the straight seal line, and the solid bulk region are made of a same material.
