Abstract:
1. A thin film transistor substrate, comprising: a first conductive line arranged in a first direction on an insulating substrate; a second conductive line arranged on the same layer as the first conductive line, the second conductive layer arranged at least partially in a second direction; a first insulating layer arranged on the first conductive line and the second conductive line; a semiconductor layer arranged on the first insulating layer; a third conductive line arranged on the first insulating layer and crossing the first conductive line and the second conductive line; a source electrode that protrudes from the third conductive line and at least partially overlaps with the semiconductor layer; a drain electrode opposing the source electrode and comprising an electrode portion, which overlaps with the semiconductor layer, and an extended portion, which extends from the electrode portion; a second insulating layer arranged on the drain electrode and comprising a contact hole that partially exposes the extended portion of the drain electrode and does not overlap with the second conductive line; and a pixel electrode arranged on the second insulating layer and electrically connected with the extended portion of the drain electrode through the contact hole.
