Abstract
A method of manufacturing an alignment film is provided, and has steps of determining printing regions for an alignment agent, which including display portions and transfer portions; printing the alignment agent within the printing regions to form an alignment thin layer; and performing an alignment process to the alignment thin layer to form the alignment film. The unevenness on the edge of the alignment film is moved away from the display portions by expanding the printing regions for the alignment agent, so as to promote the imaging quality of the finished LCD.

A method of manufacturing an alignment film, comprising steps of:
- determining printing regions for an alignment agent, wherein the printing regions include display portions and transfer portions respectively on an array substrate and a color filter substrate;
- printing the alignment agent within the printing regions to form an alignment thin layer;
- after the alignment thin layer is formed, applying a stripping agent within the transfer portions, wherein the stripping agent is used for dissolving the alignment thin layer covered on the transfer portions;
- after the alignment thin layer covered on the transfer portions is dissolved, cleaning the transfer portions for removing the stripping agent and impurities generated during dissolving the alignment thin layer;
- and
- after cleaning the transfer portions, performing an alignment process to the alignment thin layer to form the alignment film.
A method of manufacturing an alignment film, comprising steps of:
- determining printing regions for an alignment agent, wherein the printing regions are located on surfaces an array substrate and a color filter substrate for combining with each other;
- printing the alignment agent within the printing regions;
- pre-curing the alignment agent to form an alignment thin layer;
- after the alignment thin layer is formed, applying a stripping agent within the printing regions except on display portions to carry out a stripping process, wherein the stripping agent is used for dissolving the alignment thin layer covered on the transfer portions;
- after the alignment thin layer covered on the transfer portions is dissolved, removing impurities generated by the stripping process with a cleaning process to form the alignment thin layer of the display portions;
- after the cleaning process, curing the alignment thin layer;
- and
- performing an alignment process to the alignment thin layer to form the alignment film.
