Abstract: A display apparatus includes a substrate, a first silicon-based transistor including a first semiconductor layer and a first gate electrode. The first semiconductor layer includes a silicon-based semiconductor, and the first gate electrode overlaps the first semiconductor layer, at least one insulating layer on the first gate electrode, a first oxide-based transistor including a semiconductor layer. The semiconductor layer includes an oxide-based semiconductor, a first connection electrode electrically connecting the first semiconductor layer to the semiconductor layer of the first oxide-based transistor, and a bottom metal layer disposed between the substrate and the first silicon-based transistor and overlapping a portion of the first semiconductor layer of the first silicon-based transistor. A portion of the bottom metal layer overlaps a first connection point between a portion of the first semiconductor layer and the first connection electrode.
