Light emitting device for display and display apparatus having the same

A display apparatus, comprising:

• a circuit board;
• and
• a plurality of emitters arranged on the circuit board,
• wherein at least one of the emitters includes:
• a first light emitting device including a first LED stack configured to generate light including a first peak wavelength;
• and
• a second light emitting device including a second LED stack spaced apart from the first LED stack and configured to generate light including a second peak wavelength different from the first peak wavelength;
• wherein the first light emitting device includes a plurality of first semiconductor layers including a first side surface including a region inclined at a first inclined angle, and the second light emitting device includes a plurality of second semiconductor layers including a second side surface facing the first side surface and including a region inclined at a second inclined angle different from the first inclined angle;
• the second light emitting device includes a first emission region configured to emit a shorter peak wavelength light and a second emission region configured to emit a longer peak wavelength light relative to the shorter peak wavelength light;
• and
• an area of the first emission region is smaller than an area of the second emission region.
