Abstract
A birefringence film is provided with a plurality of birefringence layers including a hybrid-aligned liquid crystalline polymer. The plurality of birefringence layers is stacked in a state in which the alignment directions of the liquid crystal polymer are identical, and the rising directions of the tilt angle of the liquid crystal polymer are identical.
Claims6
A birefringence film, comprising:
- a plurality of birefringence layers including a hybrid-aligned liquid crystalline polymer,
- wherein the plurality of birefringence layers is stacked in a state in which alignment directions of the liquid crystal polymer are identical, and rising directions of a tilt angle of the liquid crystal polymer are identical, and
- wherein an exit position of extraordinary light, from light which entered the birefringence film, is shifted from an exit position of ordinary light from the light which entered the birefringence film.
