Claim 0:
1. A display apparatus comprising:
a substrate comprising a first area, and a second area adjacent to the first area;
a plurality of first pixel circuits at the first area of the substrate, each of the plurality of first pixel circuits comprising a silicon-based transistor, and an oxide-based transistor;
a plurality of second pixel circuits at the second area of the substrate, the plurality of second pixel circuits comprising transistors;
a plurality of first light-emitting diodes at the first area of the substrate, each of the plurality of first light-emitting diodes electrically connected to one of the plurality of first pixel circuits;
a plurality of second light-emitting diodes at the second area, each of the plurality of second light-emitting diodes electrically connected to one of the plurality of second pixel circuits;
a first shielding layer at the first area, the first shielding layer comprising a shielding pattern overlapping with the silicon-based transistor of each of the plurality of first pixel circuits; and
a second shielding layer at the second area between the substrate and the plurality of second pixel circuits, the second shielding layer comprising a first through-hole penetrating through the second shielding layer,
wherein the second area comprises a transmission area which is spaced apart from the plurality of second pixel circuits, and the first through-hole overlaps the transmission area, and
wherein the first shielding layer and the second shielding layer comprise different materials from each other.
