Abstract

A liquid crystal display includes a liquid crystal injected between upper and lower plates, wherein the upper and lower plates have electrodes respectively formed thereon, an upper alignment film formed on the upper plate and a lower alignment film formed on the lower plate, wherein only one of the alignment films on the upper plate and the lower plate is aligned in to determine an incipient alignment direction of the liquid crystal.

Description

[0001] This application claims the benefit of Korean Patent Application No. P2002-66583 filed in Korea on Oct. 30, 2002, which is hereby incorporated by reference. technical field [0002] The invention relates to a liquid crystal display, in particular to a liquid crystal display capable of improving brightness and contrast and a manufacturing method thereof. Background technique [0003] Generally, a liquid crystal display (LCD) displays an image by applying an electric field to the liquid crystal in response to a video signal to control the alignment state of the liquid crystal, and adjusting light transmission according to the video signal. Liquid crystals used in liquid crystal displays are in an intermediate state between solid and liquid, that is, fluid and stretchable. A typical liquid crystal used in a liquid crystal display so far is a twisted nematic mode (TN mode). Although the response speed of the twisted nematic mode may be different due to the physical chara...
