Abstract

A liquid crystal polymer composition comprising a liquid crystal, acrylic monomers including an acrylic monomer group (A) including a cyclic ring and an acrylic monomer group (B) including a chain structure or a cyclohexanol, and a photo initiator.

Claims (19)

1. A liquid crystal polymer composition comprising:

a liquid crystal;

acrylic monomers including an acrylic monomer group (A) including a cyclic ring and an acrylic monomer group (B) including a cyclohexanol; and

a photo initiator.

2. The liquid crystal polymer composition of claim 1 , wherein the acrylic monomer group A including a cyclic ring comprises one of isobornyl acrylate or isobornyl methacrylate.

3. The liquid crystal polymer composition of claim 1 , wherein the acrylic monomer group (B) including cyclohexanol comprises 3,3,5 trimethyl cyclohexanol acrylate.

4. The liquid crystal polymer composition of claim 1 , wherein a content ratio between the liquid crystal and the acrylic monomers is 8:2 to 9:1.
