Display apparatus

A display apparatus comprising:

• a substrate comprising a display area and a peripheral area outside the display area;
• a pixel circuit disposed on the substrate in the display area, wherein the pixel circuit comprises a driving thin film transistor;
• a display element connected to the pixel circuit;
• and
• an embedded driving circuit disposed on the substrate in the peripheral area, wherein the embedded driving circuit comprises a peripheral thin film transistor,
• wherein the driving thin film transistor comprises a driving semiconductor layer having a single layer structure,
• the peripheral thin film transistor comprises a peripheral semiconductor layer in which a first layer, a second layer, and a third layer, which are oxide semiconductors, are sequentially stacked one on another, wherein the second layer is disposed between the first layer and the third layer, and
• a conductivity of the second layer of the peripheral semiconductor layer is greater than respective conductivities of the first layer and the third layer of the peripheral semiconductor layer.
