Abstract
A display apparatus includes: a substrate including 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 including 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 including transistors; a first shielding layer at the first area, the first shielding layer including 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, the second shielding layer including a first through-hole between adjacent second pixel circuits from among the plurality of second pixel circuits. The first shielding layer and the second shielding layer include different materials from each other.
