1. A light emitting device comprising:
a printed circuit board having a front surface and a rear surface;
at least one light source disposed on the front surface and configured to emit light in a direction away from the printed circuit board; and
a light transmittable material disposed on the printed circuit board and covering the light source,
wherein the light source includes:
a light emitter disposed on the printed circuit board;
an insulation material disposed on the light emitter; and
bump electrodes configured to electrically connect the light emitter and the printed circuit board,
wherein the light transmittable material has a groove region formed on a surface of the light transmittable material,
wherein the bump electrodes are spaced apart from one another and differ in size from one another, and
wherein the light transmittable material has a first thickness and is configured to transmit light emitted from the light source, the light transmittable material covering the front surface of the printed circuit board extending from an upper surface of the light source.
