Patent ID: 8506841

Claim:
A photopolymerizable liquid crystal mixture, comprising: a first photopolymerizable monomer, comprising dodecyl acrylate; a second photopolymerizable monomer, comprising derivatives of cinnamic acid, and the second photopolymerizable monomer being different from the first photopolymerizable monomer; a first photoinitiator; a second photoinitiator, being different from the first photoinitiator; and a liquid crystal material; wherein photopolymerization of the first photopolymerizable monomer is induced by the first photoinitiator under an irradiation of light with a first wavelength, photopolymerization of the second photopolymerizable monomer is induced by the second photoinitiator under an irradiation of light with a second wavelength, and the first wavelength is different from the second wavelength.
