본 발명은 액정표시소자의 패널 구조에 관한 것으로, 특히 상·하판의 화소(pixel) 전극을 서로 엇갈리게 패터닝하여 4 도메인을 형성함으로써 제조 공정 및 제조 비용이 증가하지 않고도 광시야각과 빠른 응답 속도를 얻을 수 있는 액정표시소자의 패널 구조에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a panel structure of a liquid crystal display device. In particular, by forming four domains by alternately patterning upper and lower pixel electrodes, a wide viewing angle and fast response speed can be obtained without increasing a manufacturing process and manufacturing cost. It relates to a panel structure of a liquid crystal display device that can be.

일반적으로, 액정표시소자(LCD)는 보는 각도에 따라서 대비비가 변화되는 특성을 가지고 있다. 이 변화되는 정도를 시야각(Viewing Angle)으로 나타낸다. 시야각은 좌우에 따라 대비비가 어느 값 이상이 되는 각도로 표현한다. 액정셀에서는 빛이 입사되는 각도에 따라 투과율의 급격한 변화가 발생된다. 그러므로 켜짐과 꺼짐 구동에서 이 투과율의 변화로 인하여 대비비의 변화가 발생된다.In general, the liquid crystal display (LCD) has a characteristic that the contrast ratio changes according to the viewing angle. The degree of this change is represented by a viewing angle. The viewing angle is expressed as an angle at which the contrast ratio becomes more than a certain value along the left and right. In the liquid crystal cell, a sudden change in transmittance occurs according to the angle at which light is incident. Therefore, in the on and off driving, the change in the contrast ratio is caused by the change in the transmittance.

현재 모니터용 액정표시소자(LCD)에서 요구되는 광시야각과 동화상을 구현하기 위해 요구되는 빠른 응답 속도를 얻기 위한 모드로써 시야각 모드가 많이 개발되고 있다.Currently, many viewing angle modes have been developed as a mode for obtaining a fast response speed required for realizing a wide viewing angle and a moving image required in a liquid crystal display device (LCD).

그러나, 종래의 액정표시소자의 패널 구조에 있어서는, 광시야각과 동화상을 구현하기 위해 요구되는 빠른 응답 속도를 얻기 위해, 상판에 돌기를 형성시켜 광시야각을 구현하였으나 이는 공정이 복잡해지고 제조 비용이 증가하는 문제점이 있었다.However, in the panel structure of the conventional liquid crystal display device, in order to obtain a fast response speed required for implementing a wide viewing angle and a moving image, a projection is formed on the top plate to realize a wide viewing angle, but this increases the complexity and manufacturing cost. There was a problem.

따라서, 본 발명은 상기 문제점을 해결하기 위하여 이루어진 것으로, 본 발명은 상·하판의 상부 전극과 하부 전극을 서로 엇갈리게 패터닝하여 4개의 도메인(domain)을 형성함으로써 제조 공정 및 제조 비용이 증가하지 않고도 광시야각과 빠른 응답 속도를 얻을 수 있는 액정표시소자의 패널 구조를 제공하는데 그 목적이 있다.Accordingly, the present invention has been made to solve the above problems, and the present invention is to form the four domains by alternately patterning the upper and lower electrodes of the upper and lower plates to form a light without increasing the manufacturing process and manufacturing cost It is an object of the present invention to provide a panel structure of a liquid crystal display device capable of obtaining a viewing angle and a fast response speed.

상기 목적을 달성하기 위하여, 본 발명에 의한 액정표시소자의 패널 구조는, 액정이 주입될 수 있도록 일정한 간격으로 대향 배치되는 상부 및 하부 기판과, 상기 상부 기판 및 하부 기판 안쪽 상의 각각에 서로 엇갈리게 패터닝되게 형성되어 4개의 도메인을 형성하는 상부전극 및 하부전극과, 상기 상부전극과 상기 상부기판 사이에 형성된 컬러필터를 포함한다.In order to achieve the above object, the panel structure of the liquid crystal display device according to the present invention, the upper and lower substrates which are arranged at regular intervals so that the liquid crystal can be injected, and alternately patterned on each of the inside of the upper substrate and the lower substrate And an upper electrode and a lower electrode formed to form four domains, and a color filter formed between the upper electrode and the upper substrate.
