ABSTRACT:
A liquid crystal display apparatus for improving display quality and a method of manufacturing the same are provided. The liquid crystal display includes an insulating layer having a contact hole formed on a first substrate on which switching devices and a first electrode are formed, a first alignment film formed on the first electrode. The contact hole is defined by a sidewall having first and second sidewalls. The first sidewall forms a first inclined angle with respect to the first substrate, and the second sidewall faces the first sidewall. An alignment film has alignment grooves aligned in a first direction, or from the first sidewall to the second sidewall. Accordingly, the rubbing force is enhanced in the vicinities of the contact hole, to thereby enhance the LCD apparatus display quality.
