Light-emitting diode unit for display comprising plurality of pixels and display device having same

A light-emitting diode (LED) unit for a display, comprising:

• a plurality of pixels each including:
• a first light emitting cell, a second light emitting cell, and a third light emitting cell, each of the first, second, and third light emitting cells including a first conductivity type semiconductor layer, an active layer, and a second conductivity type semiconductor layer;
• a first wavelength converter configured to convert a wavelength of light emitted from the first light emitting cell;
• a second wavelength converter configured to convert a wavelength of light emitted from the second light emitting cell;
• and
• pads electrically connected to the first, second, and third light emitting cells to independently drive the first, second, and third light emitting cells,
• wherein the first, second, and third light emitting cells of each pixel overlap at least one of the pads.
