Abstract

A thin film transistor (TFT) array panel includes: first and second pixel electrodes neighboring each other; a data line extending between the first and the second pixel electrodes; first and second gate lines extending perpendicularly to the data line; a first TFT including a first gate electrode connected to the first gate line, a first source electrode connected to the data line, and a first drain electrode facing the first source electrode and connected to the first pixel electrode; and a second TFT including a second gate electrode connected to the second gate line, a second source electrode connected to the data line, and a second drain electrode facing the second source electrode and connected to the second pixel electrode. The first source electrode has the same relative position with respect to the first drain electrode as the second source electrode with respect to the second drain electrode.
