Light emitting device having a first light emitting device and a second light emitting device disposed laterally adjacent thereto, and display apparatus including the light emitting device

A display apparatus, comprising:

• a circuit board;
• and
• a light emitting device disposed on the circuit board, the light emitting device comprising:
• a substrate;
• an adhesive layer disposed on an upper surface of the substrate;
• a first light emitting device;
• a second light emitting device disposed laterally adjacent to the first light emitting device;
• a first cover layer covering the first light emitting device and the second light emitting device;
• and
• connection layers disposed on the first cover layer, and electrically connected to the first and second light emitting devices,
• wherein:
• the adhesive layer has a first thickness over a first region of the substrate above which the first and second light emitting devices are disposed, and a second thickness, different from the first thickness, over a second region of the substrate above which the first and second light emitting devices are not disposed;
• the first light emitting device includes a first light emitting structure;
• the second light emitting device includes a second light emitting structure and a third light emitting structure;
• the first light emitting structure is configured to emit light having a peak wavelength longer than peak wavelengths of light emitted from the second or third light emitting structures;
• the second and third light emitting structures are configured to emit light having different peak wavelengths from each other;
• and
• a vertical height of a side surface of the first light emitting structure is less than a sum of vertical heights of side surfaces of the second and third light emitting structures.
