Abstract: | We report a method for fabricating a cholesteric liquid crystal capsule display wherein the red, green, and blue capsules are separated in the subpixels with a width of 200 μm. The mixture of a photo-isomerizable chiral dopant and a nematic liquid crystal was encapsulated by an emulsification technique, and then directly printed onto a plastic substrate. A UV light with different amount of energy was exposed through a shadow photomask, and consequently, the red, green, and blue colors were separately induced in each subpixels zone. |
