Control signal unit for a liquid crystal display and a method for fabricating the same

A method of fabricating a liquid crystal display, comprising the steps of:

• forming a gate line assembly and control signal lines on a substrate, the gate line assembly comprising gate electrodes and gate lines;
• forming a gate insulating layer such that the gate insulating layer covers the gate line assembly and the control signal lines;
• forming semiconductor patterns on the gate insulating layer;
• forming a data line assembly with data lines crossing over the gate lines, source electrodes contacting the one-sided semiconductor patterns, and drain electrodes contacting the other-sided semiconductor patterns in correspondence with the source electrodes;
• forming a protective layer such that the protective layer covers the data line assembly and the semiconductor patterns;
• forming first contact holes and second contact holes with predetermined width such that the first contact holes expose the drain electrodes, and the second contact holes expose the control signal lines, wherein each second contact hole has a lateral side bordering on the control signal line, the lateral side of the second contact hole being longer than the width of the second contact hole;
• and
• forming pixel electrodes and subsidiary control signal pads such that the pixel electrodes are connected to the drain electrodes through the first contact holes, and the subsidiary control signal pads are connected to the control signal lines through the second contact holes.
