11. A display apparatus comprising:
a buffer layer disposed over a substrate;
a semiconductor layer disposed over the buffer layer; and
a display device electrically connected to the semiconductor layer,
wherein the semiconductor layer includes:
a first area doped with a first conductivity type and disposed adjacent to an upper surface of the semiconductor layer,
a second area spaced apart from the first area, doped with the first conductivity type, and disposed adjacent to the upper surface of the semiconductor layer,
a third area doped with a second conductivity type different from the first conductivity type and disposed under the first area, and
a fourth area doped with the second conductivity type and disposed under the second area.
