A display device according to an embodiment includes: a substrate; a first conductive layer positioned on the substrate; a semiconductor layer positioned on the first conductive layer; a second conductive layer positioned on the semiconductor layer; an oxygen supply layer positioned under the second conductive layer, in contact with the second conductive layer, and having the same planar shape as the second conductive layer; and a light-emitting element connected to the second conductive layer, wherein the oxygen supply layer includes a metal oxide that includes one or more of indium, zinc, tin, or gallium, or alloys thereof.

Display device and manufacturing method thereof

A liquid crystal display includes: a gate line connected to a gate electrode; a semiconductor layer disposed on the gate line and including silicon; an ohmic contact layer disposed on the semiconductor layer; and a data conductor disposed on the ohmic contact layer. The semiconductor layer includes a source region, a drain region, and a channel region disposed between the source region and the drain region. The data conductor includes a data line transmitting a data signal, a source electrode corresponding to the source region, and a drain electrode corresponding to the drain region. A channel step of the semiconductor layer is a height difference between an upper surface in the source region or the drain region and an upper surface in the channel region. The upper surface in the source region or the drain region has a maximum height of the semiconductor layer.
