Abstract
A display apparatus includes: a substrate; a first semiconductor layer on the substrate, and including a silicon semiconductor; a second semiconductor layer on the first semiconductor layer, and including an oxide semiconductor; a first conductive layer on the second semiconductor layer; at least one metal layer between the first semiconductor layer and the first conductive layer; and a first contact hole to electrically connect the first semiconductor layer to the first conductive layer. An inner surface of the first contact hole includes a side surface of the at least one metal layer.
