A light emitting device is provided with a growing base having specific geometry to prevent delamination between the encapsulant and the growing base, and thereby enhance structural reliability of the light emitting device. Furthermore, the light emitting efficiency as well as uniformity of light output of the light emitting device can be improved by forming the side surface of the growing base with at least a curved portion or slanted portion, and uneven structures can be formed on the curved portion or slanted portion to further improve the uniformity of light output. Furthermore, the light emitting diode chips can be fabricated by taking batch processing on the growing substrate, as provided in the wafer-level structure, with the advantages of saving cost, improving yield, etc.
