Title:
LIQUID CRYSTAL DISPLAY DEVICE AND METHOD FOR MANUFACTURING LIQUID CRYSTAL DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/061918
Kind Code:
A1
Abstract:
A liquid crystal display device provided with a first substrate, a second substrate, a liquid crystal layer including a negative-type liquid crystal material sandwiched between the first substrate and the second substrate, a first alignment film provided to the surface of the first substrate on the liquid crystal layer side thereof, a first phase difference layer having birefringence provided between the first substrate and the first alignment film, and a second alignment film provided to the surface of the second substrate on the liquid crystal layer side thereof, the first alignment film and/or the second alignment film being an optical alignment film which is in contact with the liquid crystal layer and which imparts a pretilt angle of 75° to less than 90° to the liquid crystal material, the first phase difference layer being formed from a first polymeric material having a first photofunctional group, the optical alignment film being formed from a second polymeric material having a second photofunctional group, and the first photofunctional group and the second photofunctional group being groups that generate at least one of an isomerization reaction, a dimerization reaction, a Fries rearrangement reaction, and a cleavage reaction.
