1. A display apparatus comprising:
an organic light-emitting diode;
a driving transistor configured to control an amount of current flowing from a second node to the organic light-emitting diode according to a voltage applied to a first node, the second node being electrically connected to a power voltage line;
a first bottom metal layer disposed below the driving transistor and electrically connected to the driving transistor; and
a first initialization transistor connected between the first node and a first initialization voltage line,
wherein the first bottom metal layer electrically connects the driving transistor to the first initialization transistor, and
wherein, when viewed from a direction perpendicular to the first bottom metal layer, the first bottom metal layer overlaps the first initialization semiconductor layer.
