Abstract
A method for manufacturing a thin film transistor array panel for a liquid crystal display is disclosed. The present invention enables to manufacture a thin film transistor array panel in lesser steps than the conventional method by fabricating certain film layers on the panel in one photolithography process. For this purpose, a mask that has parts of different light transmittance is used to fabricate multiple film layers in one photolithography process. The method according to the present invention can increase the productivity and yield by reducing the number of photolithography steps, which are expensive and time consuming.
