Abstract:
A TFT substrate with reduced pixel defect rate is presented. The TFT substrate includes a pixel electrode, a negative line to apply a reverse voltage to the pixel electrode, and a recovery transistor including a drain electrode overlapping a part of the negative line with a insulating layer disposed between the negative line and the drain electrode. A contact hole is formed on the negative line and the drain electrode, and a bridge electrode connects the negative line and the drain electrode through the contact hole.The thin film transistor substrate and a display apparatus presented herein protect a data line assembly metal layer and decrease pixel defect. An improved reverse voltage efficiency is applied to a pixel electrode to protect a drain electrode.
