1. A display apparatus comprising:
a display substrate;
light emitting devices arranged over an upper surface of the display substrate, one or more light emitting devices comprising:
a first LED unit comprising a first light emitter;
a second LED unit comprising a second light emitter; and
a third LED unit comprising a third light emitter; and
a module substrate disposed between the display substrate and the light emitting devices and having a first surface on which the light emitting devices are arranged along a direction parallel to the first surface and a second surface opposite to the first surface; and
a driver disposed on the second surface of the module substrate, and
wherein the second LED unit is disposed between the first LED unit and the third LED unit,
each of the first, the second and the third light emitters comprises a first conductivity type semiconductor layer and a second conductivity type semiconductor layer,
the first conductivity type semiconductor layer and the second conductivity type semiconductor layer in each of the first, the second, and the third light emitters are disposed perpendicular to the upper surface of the display substrate and stacked in a horizontal direction with respect to the upper surface of the display substrate,
the module substrate comprises a connector formed on the module substrate and electrically connecting the light emitting devices to the driver.
