Method of forming alignment film

摘要

A method of forming an alignment film is provided. A photosensitive polymer material is provided, wherein the photosensitive polymer material defines a first pixel area and a second pixel area respectively defining a first sub-pixel area and the second sub-pixel area. In a first exposure, the photosensitive polymer material is irradiate by a first exposure light and a second exposure light to form a first alignment portion and a second alignment portion with different alignment directions in the first sub-pixel of the first pixel area and the second sub-pixel of the second pixel area respectively. In a second exposure, the photosensitive polymer material is irradiated with the first exposure light and the second exposure light to form a third alignment portion and a fourth alignment portion with different alignment directions in the first sub-pixel of the second pixel area and the second sub-pixel of the first pixel area respectively.

1. A method of forming an alignment film, comprising:
providing a photosensitive polymer material, wherein the photosensitive polymer material defines a first pixel area and a second pixel area each defining a first sub-pixel area and a second sub-pixel area; in a first exposure, irradiating the photosensitive polymer material with a first exposure light and a second exposure light to form a first alignment portion and a second alignment portion in the first sub-pixel area of the first pixel area and the second sub-pixel area of the second pixel area respectively, wherein the alignment direction of the first alignment portion is different from that of the second alignment portion; in a second exposure, irradiating the photosensitive polymer material with the first exposure light and the second exposure light to form a third alignment portion and a fourth alignment portion in the second sub-pixel area of the first pixel area and the first sub-pixel area of the second pixel area respectively, wherein the alignment direction of the third alignment portion is different from that of the fourth alignment portion.
