Abstract

An exemplary liquid crystal display includes two substrates (21, 22) opposite to each other and spaced apart a predetermined distance, each of the substrates having an alignment layer (211, 221); a liquid crystal layer (23) between the two substrates, and having a plurality of liquid crystal molecules; and a plurality of gate lines (241) formed between one alignment layer and one substrate. The two alignment layers have two orthogonal aligning directions, one aligning direction of the two alignment layers being parallel to an extending direction of the gate lines.
