Abstract: A thin film transistor (TFT) substrate includes a base substrate, a TFT disposed on the base substrate. The TFT includes a gate electrode, a semiconductor layer comprising a channel region, and a source electrode and a drain electrode spaced apart from one another by a length of the channel region. The TFT substrate further includes a gate insulating layer disposed between the gate electrode and the semiconductor layer and a measuring pattern configured to measure a length of the channel region.
