Stable Photopatterned Cholesteric Layers Made by Photoisomerization and Subsequent Photopolymerization for Use as Color Filters in Liquid-Crystal Displays

Very stable cholesteric layers with patterned reflection colors are made by coating a monomeric cholesteric mixture on a substrate followed by photoisomerization in air to tune the reflection color and photopolymerization to stabilize the layer. The layers can be used as color filters in liquid‐crys...

Description
Summary:Very stable cholesteric layers with patterned reflection colors are made by coating a monomeric cholesteric mixture on a substrate followed by photoisomerization in air to tune the reflection color and photopolymerization to stabilize the layer. The layers can be used as color filters in liquid‐crystal displays (see Figure). The photopolymerization is performed in N2, resulting in rapid crosslinking, preventing unwanted additional color changes.
