Claims
- 1. A liquid crystal display cell comprising an oriented liquid crystal layer disposed between two plates which are provided with transparent electrode layers disposed on the inner sides of said plates, and orientation layers disposed on the inner sides of the electrode layers and aligning the adjacent liquid crystal molecules in predetermined directions, at least one of said orientation layers comprising an oriented linearly polarized light modified photopolymer.
- 2. The liquid crystal display cell according to claim 1, wherein the predetermined directions on the two plates are different.
- 3. The liquid crystal display cell according to claim 1, wherein a nematic liquid crystal is linearly oriented by the orientation layers in a predetermined direction, the tilt angle .theta. between the nematic direction and the substrate surface being between 0.ltoreq..theta.<85.degree..
- 4. The liquid crystal display cell according to claim 1, further comprising a pattern of regions with different predetermined orientations.
- 5. The liquid crystal display cell according to claim 1, further comprising a pattern or regions with predetermined orientation and non-oriented regions.
- 6. The liquid crystal display cell according to claim 3, wherein the two plates have different orientation patterns differing with respect to different predetermined orientations and resulting in different twist angles of the liquid crystal.
