Abstract
The invention provide a fabrication method for a color cholesteric liquid crystal display device, comprising: providing a first substrate; forming a patterned enclosed structure on the first substrate, wherein the patterned enclosed structure comprises a plurality of stripe wall structures, and one end of each stripe wall structure is connected to and perpendicular to a straight seal line, thereby dividing a first LC channel with a first opening, a second closed LC channel, and a third closed LC channel, and the length of the first LC channel exceeds that of the second LC channel, and the length of the second LC channel exceeds that of the third LC channel; providing a second substrate with an adhesion layer formed thereon; assembling the first substrate and the second substrate to tightly seal the adhesion layer and the patterned enclosed structure.
