  • Method of forming alignment film
    Patent number: 8802358
    Abstract: 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.
