The purpose of the present invention is to provide an organic light emitting device capable of preventing light from the outside from being emitted and reflected on a lateral side of a wire. The organic light emitting device according to an embodiment of the present invention comprises: a first substrate; a switching and driving thin film transistor arranged on the first substrate; a pixel electrode connected to the driving thin film transistor; a pixel definition film which is arranged on an edge part of the pixel electrode and a planarization film, and includes an opening unit to expose the pixel electrode; an organic light emitting layer arranged on the pixel electrode inside the opening unit; and a common electrode arranged on the organic light emitting layer. The pixel definition film includes at least one among thermosensitive discoloration paint, organic black paint, and dyes, and a base resin. |
