Abstract:
1. 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 and the other end of the stripe wall structures connects to a solid bulk region, 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, wherein the width of the solid bulk region is relatively larger than the width of the stripe wall structures and the solid bulk region does not include a channel therein; 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; injecting a first color liquid crystal in the first LC channel and sealing the first LC channel with a first seal material; cutting the assembly to expose a second opening of the second LC channel, wherein a portion of the solid bulk region remains, so that the third LC channel is enclosed after cutting the assembly; injecting a second color liquid crystal in the second LC channel and sealing the second LC channel with a second seal material; cutting the assembly to expose a third opening of the third LC channel; and injecting a third color liquid crystal in the third LC channel and sealing the third LC channel with a third seal material.
