Light emitting device and manufacturing method of the same

A light emitting device comprising:

• a thin film transistor;
• a first electrode connected to one of a source of the thin film transistor and a drain of the thin film transistor,
• an insulating material covering an end portion of the first electrode,
• a second electrode covering a side face of the insulating material and contacting with the first electrode,
• a light emitting layer comprising an organic material on the second electrode and a first portion of the insulating material,
• a third electrode in contact with the light emitting layer comprising the organic material and a second portion of the insulating material, and
• an auxiliary electrode on the insulating material and in contact with the third electrode,
• wherein the second electrode reflects a light emitted from the light emitting layer comprising the organic material, and
• wherein the third electrode is a conductive film through which a light is transmitted.
