Abstract

본 발명은 박막 트랜지스터형 액정표시소자를 개시한다. 이 액정표시소자는 두 행의 화소전극 사이에 주사선 2개가 같이 나란히 배치되어 있고, 개개의 주사선은 인접한 화소전극을 스위칭하기 위한 각각의 박막 트랜지스터의 게이트와 연결되며, 두 행의 같은 열의 화소의 박막 트랜지스터의 소오스 전극이 공유되며, 보존전기용량의 공통전극은 인접열의 같은 행 화소전극 사이를 지나면서 화소전극과 겹치게 되어 세로측 블랙 매트릭스 역할을 한다.The present invention discloses a thin film transistor type liquid crystal display element. In this liquid crystal display element, two scanning lines are arranged side by side between two pixel electrodes, and each scanning line is connected to the gate of each thin film transistor for switching adjacent pixel electrodes, The source electrode of the transistor is shared, and the common electrode of the storage capacitance overlaps the pixel electrode while passing between the pixel electrodes of the same row in the adjacent column, thereby serving as a vertical black matrix.
