Abstract: A pixel structure of a display apparatus includes an electrode line, at least one ultra small light-emitting diode, and a connection electrode. The electrode line includes a second electrode separated from a first electrode and at a same level as the first electrode on a base substrate. The at least one ultra small light-emitting diode is on the base substrate and has a length less than a distance between the first and second electrodes. A connection electrode includes a first contact electrode connecting the first electrode to the ultra small light-emitting diode and a second contact electrode connecting the second electrode to the ultra small light-emitting diode.
