1. A display apparatus comprising:
a substrate; and
a plurality of pixel regions and at least one separation region defined therebetween on the substrate, each of the pixel regions comprising:
a first LED stack having a first side surface forming a first angle with the substrate;
a second LED stack adjacent to the first LED stack and having a second side surface forming a second angle with the substrate;
a third LED stack adjacent to the second LED stack and having a third side surface forming a third angle of between 45 and 85 degrees with the substrate;
electrode pads electrically connected to the first, second, and third LED stacks, the electrode pads comprising a common electrode pad, a first electrode pad, a second electrode pad, and a third electrode pad; and
an insulation layer disposed on at least one of the first, second, and third LED stacks,
wherein:
the common electrode pad is connected to the first, second, and third LED stacks;
the first, second, and third electrode pads are connected to the first, second, and third LED stacks, respectively;
the first, second, and third LED stacks are configured to be independently driven using the electrode pads;
the first LED stack is configured to emit light having a longer peak wavelength than that emitted from the second and third LED stacks; and
the first angle is different from the second and third angles.
