Light emitting device and display apparatus including the same

A light emitting device comprising:

• a substrate;
• a first light emitting cell, a second light emitting cell, and a third light emitting cell respectively disposed on the substrate and configured to respectively emit red light, green light, and blue light through an upper surface thereof;
• pads electrically connected to the first, second, and third light emitting cells;
• partition walls disposed between of the first light emitting cell, the second light emitting cell, and the third light emitting cell, respectively, and configured to not transmit light, the partition walls having upper surfaces facing the same direction as the upper surfaces of the first, second, and third light emitting cells;
• and
• a protective layer covering the first, second, and third light emitting cells and disposed on the upper surfaces of the partition walls, and filling at least a portion of an area defined between adjacent partition walls,
• wherein:
• each of the first, second, and third light emitting cells has an upper surface facing away from the substrate and through which light exists the corresponding light emitting cell, and a lower surface opposite to the upper surface;
• the pads are disposed on the lower surfaces of the first, second, and third light emitting cells;
• a height of each of the first, second, and third light emitting cells is lower than a height of each partition wall;
• and
• a distance between the partition walls and the first, second, and third light emitting cells is less than about 5 μm.
