Abstract

본 발명은 액티브 매트릭스 액정표시소자에 관한 것으로, 종래 액티브 매트릭스 액정표시소자는 트랜지스터 제조시 기판을 비정질이나 폴리형반도체로 제조하기 때문에 트랜지스터 특성이 저하되는 문제점이 발생하고, 이로인해 같은 기판상에 반도체기술을 이용란 구동회로를 형성할 수 없는 문제점이 있었다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an active matrix liquid crystal display device. In the conventional active matrix liquid crystal display device, since a substrate is made of amorphous or poly-semiconductor during transistor manufacturing, there is a problem in that transistor characteristics are degraded. There is a problem in that it is impossible to form a driving circuit using technology.

본 발명은 이러한 문제점을 해결하기 위하여 기판을 단결정반도체로 제조함으로써 트랜지스터 특성이 향상되고, 또한 같은 기판상에 구동회로를 형성할 수 있어 구동회로를 형성하기 위한 추가공정이 필요없게 되어 공정 및 생산단가가 낮아지며, 소자의 크기를 줄일 수 있게 된다.In order to solve these problems, the present invention improves transistor characteristics by manufacturing a substrate as a single crystal semiconductor, and also can form a driving circuit on the same substrate, thereby eliminating the need for an additional process for forming the driving circuit. Lowers the size of the device can be reduced.
