Abstract
The purpose of the present invention is to improve, in connection with a display device using a semiconductor light-emitting element configured for active matrix (AM) driving, flicker caused by leakage from a switch TFT by increasing the capacitance value of a capacitance. To this end, the display device using a semiconductor light-emitting element may comprise: a driving TFT for driving the semiconductor light-emitting element; a switch TFT for receiving a scan signal to be turned on or off and transmitting a data signal to the driving TFT; a first capacitance formed between a first metal layer connected to a gate terminal of the driving TFT and a second metal layer connected to a source terminal or a drain terminal of the driving TFT; and a second capacitance formed between an active layer of the driving TFT and the second metal layer.
