1. A display apparatus comprising:
a substrate comprising a main display area, a component area including a transmission area, and a peripheral area at an outer side of the main display area;
a buffer layer above the substrate;
a main pixel circuit at the main display area, and comprising a main semiconductor layer above the buffer layer;
an auxiliary pixel circuit at the component area, and comprising a first wire and an auxiliary semiconductor layer spaced apart from the main semiconductor layer;
an auxiliary pixel electrode on the auxiliary pixel circuit of the component area; and
a bottom metal layer between the substrate corresponding to the component area and the auxiliary pixel circuit, and electrically connected to the first wire,
wherein the bottom metal layer has a hole at the transmission area of the component area to allow light to be transmitted through the hole of the bottom metal layer at the transmission area, and the buffer layer covers a side surface of the bottom metal layer facing the hole.
