Abstract
Disclosed is a light emitting diode having a multi-cell structure including a number of unit cells. The light emitting diode is capable of reducing light loss of the light emitting diode surface and improving light efficiency by bonding pads to be formed for contact between mesa etching regions for forming an electrode of the existing n-type semiconductor layers and p-type semiconductor layers. The light emitting diode is also capable of controlling chip size and manufacturing chips of different sizes from each other even when going through the same chip manufacturing process as the related art.
