Patent ID: 6888585

Claim:
A liquid crystal display, comprising: a substrate; a gate line assembly and a plurality of signal lines formed on the substrate, the gate line assembly comprising gate electrodes and gate lines; a gate insulating layer covering the gate line assembly and the signal lines; thin film transistor semiconductor patterns formed on the gate insulating layer; a data line assembly comprising data lines crossing over the gate lines while being insulated from the gate lines, source electrodes extended from the data lines while contacting the semiconductor patterns, and drain electrodes contacting the semiconductor patterns in correspondence with the source electrodes; a protective layer covering the data line assembly and the semiconductor patterns; first contact holes exposing the drain electrodes; second contact holes exposing the respective signal lines with a predetermined width, the second contact holes having a lateral side bordering on the signal line, the lateral side of the second contact holes having a length greater than the width of the second contact holes; and pixel electrodes and subsidiary signal pads standing in the same plane, the pixel electrodes being connected to the drain electrodes, the subsidiary signal pads being connected to the signal lines.
