Method for aligning liquid crystal display substrate and method for manufacturing liquid crystal display

The invention provides a method for aligning a liquid crystal display substrate and a method for manufacturing a liquid crystal display. The method for aligning the liquid crystal display substrate comprises the following steps of: forming an alignment film containing a plurality of solidifiable molecules on the substrate and applying an electric field to the substrate to rotate the solidifiable molecules; and solidifying the solidifiable molecules to make at least two adjacent solidifiable molecules cross-linked with each other. Therefore, the alignment film has uniform alignment property.
