1. A light emitting diode display apparatus, comprising:
a pixel disposed on a substrate and configured to display an image,
wherein the pixel includes:
a transistor including a gate electrode, a semiconductor layer, a source electrode, and a drain electrode;
a first light emitting portion configured to electrically connect to a first driving power line;
a second light emitting portion configured to electrically connect to a second driving power line;
a common power line configured to electrically connect the first light emitting portion and the second light emitting portion in common;
a light emitting diode having an upper surface, a sidewall, and a bottom surface;
a first electrode on the upper surface of the light emitting diode electrically connected to the source electrode;
a second electrode on the bottom surface of the light emitting diode electrically connected to the common power line;
a passivation layer on the thin film transistor;
a planarization layer on the light emitting diode to cover the light emitting diode; and
an adhesive member between the passivation layer and the light emitting diode.
