Patent 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 that are sequentially 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 a part of the pixel electrode overlaps one of a source and drain electrodes.
