Abstract
A method of darkening a defective pixel including a short between a source electrode and a drain electrode in a thin film transistor substrate includes forming a gate line and a data line on a substrate to define a pixel region; forming a thin film transistor at a crossing of the gate line and the data line, the thin film transistor having a gate electrode, a source electrode and a drain electrode; forming a pixel electrode and a common electrode in the pixel region; forming a common line provided in parallel to the gate line and connected to the common electrode; forming an extended part of the drain electrode in parallel to the gate line; and cutting the extended part along a cutting line.
