Abstract
A TFT-LCD comprising: a gate line extended in one direction on an insulating substrate; a semiconductor layer pattern superposed on the gate line, one end of the semiconductor layer pattern being projected from both sides of the gate line, the other end of the semiconductor layer pattern being projected in one direction from the one side of the gate line; a data line intersected with the gate line, and superposed on a portion of the semiconductor layer pattern at the portion where the semiconductor layer pattern is projected from both sides of the gate line, the data line coming into contact with the semiconductor layer pattern at the superposed portion; and a pixel electrode connected to the other end of the semiconductor layer patter.
