Thin film transistor array panel for a liquid crystal display and methods for manufacturing the same

A method for manufacturing a thin film transistor array panel for a liquid crystal display, comprising steps of:

• forming a data wire including a data line on an insulating substrate;
• forming red, blue and green color filters at the pixels on the insulating substrate;
• forming an insulating layer covering the data wire and the color filters;
• forming a gate wire including a gate line and a gate electrode on the insulating layer;
• forming a gate insulating layer covering the gate wire on the insulating layer;
• forming a semiconductor pattern and a first contact hole exposing the data line at the insulating layer and the gate insulating layer;
• forming ohmic contact layers on the semiconductor pattern;
• and
• forming a pixel wire including a source electrode and a drain electrode on the ohmic contact layers, which are made of a same layer on the semiconductor pattern and separated from each other, and a pixel electrode connected to the drain electrode and formed on the pixels.
