ABSTRACT:
A liquid crystal display and a manufacturing method thereof are provided. The liquid crystal display includes upper and lower substrates, electrodes on each of the upper and lower substrates such that the electrodes are facing each other, a first alignment layer formed on the upper and lower substrates and formed of a material which aligns perpendicular to a rubbing direction, and a second alignment layer pattern formed on the first alignment layer and formed of a material which aligns parallel to the rubbing direction. The method for manufacturing the liquid crystal display involves a process where pixels are divided into two halves or in single units, and then each pixel having different aligning directions can be performed through one rubbing step, so that the process is simplified and damage to the surfaces of alignment layers is reduced. Thus, the angle of visibility and display quality are enhanced.
