Method for forming data lines of a liquid crystal display device

摘要

A method for forming data lines of a liquid crystal display device, wherein a double data line is adopted as a data line while the contact resistance with a transparent electrode is maintained at the same level as in the conventional art, whereby about 150 seconds of sputter equipment use time for forming the triple data line in the conventional art can be reduced to about 85 seconds by forming the double data line. The double data line of a pad part is used as a source/drain region at a TFT part, so that a CD bias at the source/drain region metal layer is improved.
