Abstract
A thin film transistor liquid crystal display (TFT-LCD) pixel unit and a method for manufacturing the same. The pixel unit comprises a gate line and a gate electrode formed on a substrate and a first gate insulating layer, an active layer, and a doped layer sequentially that are formed on the gate line and the gate electrode. An intercepting trench is formed on the gate line to cut off the doped layer and the active layer on the gate line. A second insulating layer covers the intercepting trench and the substrate where the gate line and the gate electrode are not formed. A pixel electrode is formed on the second insulating layer and is integrated with the second source/drain electrode.
Claims7
A thin film transistor liquid crystal display (TFT-LCD) pixel unit, comprising:
- a gate line and a gate electrode formed on a substrate;
- a first gate insulating layer, an active layer, and a doped layer sequentially formed on the gate line and the gate electrode;
- and
- a data line, a first source/drain electrode, and a second source/drain electrode formed on the doped layer, the first and second source/drain electrodes being separated apart from each other, the data line being electrically connected to the first source/drain electrode,
- wherein an intercepting trench is formed on the gate line to cut off the doped layer and the active layer on the gate line;
- a second insulating layer covers the intercepting trench and the substrate where the gate line and the gate electrode are not formed;
- and a pixel electrode is formed on the second insulating layer integrally with the second source/drain electrode and contacts the doped layer on the gate electrode at a position where the second source/drain electrode is formed.
