Light emitting module

A light emitting module comprising:

• a substrate;
• a first light emitting part disposed on the substrate;
• and
• a second light emitting part disposed on the substrate and spaced apart from the first light emitting part by an isolation trench between the first and the second light emitting parts;
• and
• a wavelength conversion part disposed on the first and second light emitting parts,
• wherein:
• the first light emitting part and the second light emitting part comprise a first light emitting region and a second light emitting region, respectively, the second light emitting region being spaced apart from the first light emitting region;
• the wavelength conversion part entirely surrounds at least one of the first and second light emitting parts;
• the wavelength conversion part includes a first wavelength conversion layer covering the second light emitting region, a second wavelength conversion layer covering the first light emitting region, and a barrier layer interposed between the first and second wavelength conversion layers;
• and
• the isolation trench and the barrier layer vertically overlap each other on the substrate.
