Abstract:
A method for manufacturing a thin film transistor array panel for a liquid crystal display, comprising steps of:forming a gate wire including a gate line and a gate electrode connected to the gate line on an insulating substrate; forming a gate insulating layer pattern covering the gate wire; forming a semiconductor pattern on the gate insulating layer; forming an ohmic contact layer pattern on the semiconductor pattern; forming a data wire including a source electrode and a drain electrode and a data line connected to the source electrode on the ohmic contact layer; forming color filters, said color filters covering the data wire and having a first contact hole exposing the drain electrode; and forming a pixel electrode connected to the drain electrode through the first contact hole, wherein the source electrode and the drain electrode are separated by a photolithography process using a photoresist pattern, and the photoresist pattern has a first portion having a first thickness and is at least located between the source electrode and the drain electrode, a second portion having a second thickness larger than the first portion, and a third portion having a third thickness smaller than the first thickness.
