Abstract: The present disclosure relates to a thin film transistor substrate for flat panel display including an organic light emitting diode display. The present disclosure provides a device comprising: a substrate; a scan line extending in a first direction on the substrate; a buffer layer on the scan line; a semiconductor layer extending in a second direction and crossing the scan line on the buffer layer; a gate insulating layer on the semiconductor layer; a gate electrode connected to the scan line, and extending in the first direction and crossing the semiconductor layer on the gate insulating layer; an intermediate insulating layer on the gate electrode; a data line crossing the scan line on the intermediate insulating layer; a source electrode branching from the data line and contacting a first side of the semiconductor layer; and a drain electrode facing the source electrode and contacting a second side of the semiconductor layer.

Abstract: A display device including subpixels and at least two scan lines is disclosed. The subpixels are arranged on a substrate, and each subpixel includes an emission area, in which an emission element is disposed to emit light, and a circuit area, in which a circuit for driving the emission element is disposed. The at least two scan lines are positioned in the circuit area. One or more of the at least two scan lines are formed by a metal layer different from a gate metal layer constituting gate electrodes of transistors disposed in the circuit area.
