摘要： A method of manufacturing a birefringent film is provided, by which a birefringent film including a liquid crystal compound birefringent layer and another birefringent layer can be manufactured so as to have a reduced thickness in a reduced number of process steps. In the manufacturing method, a non-liquid crystal polymer birefringent layer that has been subjected to an aligning treatment is used as an alignment layer for a liquid crystal compound. According to the manufacturing method, the process step of separately preparing an alignment layer and the need for the additional alignment layer can be eliminated, thereby allowing the total thickness of the birefringent film to be reduced.

摘要： A liquid crystal panel of the present invention has a liquid crystal cell, a visible-side polarizer disposed on the visible surface side of the liquid crystal cell, and an antivisible-side polarizer disposed on the side opposite to the antivisible surface of the liquid crystal cell. The visible-side polarizer and the antivisible-side polarizer are disposed so that the absorption axis direction of the visible-side polarizer and the absorption axis direction of the antivisible-side polarizer will be approximately parallel to each other. A polarization rotating layer that rotates linearly polarized light by approximately 45 degrees is disposed between the visible-side polarizer and the antivisible-side polarizer.This liquid crystal panel hardly undergoes distortion and can restrain leakage of light in the peripheral part. Therefore, a liquid crystal display device incorporating the liquid crystal panel is excellent in image displaying characteristics.

摘要： An inclined optical compensation film formed from a non-liquid-crystal polymer, which is useful in a TN mode liquid crystal display. A substrate is coated with a non-liquid-crystal polymer to thereby form a coating film; the non-liquid-crystal polymer of the coating film is inclined and aligned; and the coating film is solidified, thereby forming an inclined optical compensation film. The non-liquid-crystal polymer can be inclined and aligned by, for example, applying external force, such as wind blowing, to the coating film. This inclined optical compensation film exhibits, for example, a birefringence (Δn) ranging from 0.001 to 0.5 and thus is useful in a TN mode liquid crystal display, etc.
