Patent ID: 8305510

Claim:
A method for manufacturing an LCD device comprising: forming a gate line arranged in one direction on a substrate, the gate line having a predetermined portion concaved angularly and inwardly on a bottom of the gate line; forming a gate electrode projecting from the gate line; sequentially depositing a gate insulating layer, a semiconductor layer and a conductive layer on the substrate including the gate line; etching the conductive layer to form a data line overlapped with some of the concaved portion of the gate line, thereby defining a pixel region, the data line perpendicular to the gate line; forming a source electrode projecting from the data line; forming a drain electrode at a fixed interval from the source electrode on the gate insulating layer; forming an active layer by etching the semiconductor layer with the data line, the source electrode and the drain electrode as a mask; and forming a pixel electrode in the pixel region, wherein a boundary of the bottom of the gate line that overlaps the data line is greater than a width of the data line, and wherein said predetermined portion concaved angularly and inwardly on a bottom of the gate line is located in a single pixel region.
