Light emitting device and vehicular lamp including the same

A vehicular lamp comprising:

• a combination lamp;
• and
• a main lamp,
• wherein at least one of the combination lamp and the main lamp comprises:
• a light emitting unit;
• a sidewall surrounding a side surface of the light emitting unit and adjoining the side surface thereof;
• and
• a substrate disposed at a lower side of the light emitting unit and supporting the light emitting unit and the sidewall,
• wherein the light emitting unit comprises:
• a light emitting element comprising at least two light emitting cells;
• a wavelength converter disposed on the light emitting element and covering at least part of an upper surface of the light emitting element;
• a first pad electrode electrically connected to at least one of the light emitting cells;
• and
• a second pad electrode electrically connected to the other light emitting cell,
• wherein the sidewall has a protruding portion formed at an edge thereof,
• wherein the substrate comprises a base and first and second electrodes electrically connected to an external electrode to supply electric power to the light emitting unit, the first electrode and the second electrode being at least partially exposed,
• wherein the at least two light emitting cells are electrically connected to each other and each comprise an n-type semiconductor layer, a p-type semiconductor layer, and an active layer interposed between the n-type semiconductor layer and the p-type semiconductor layer.
