<p>PURPOSE: An organic light emitting device is provided to improve light extraction efficiency by forming a pattern layer between a glass substrate and an air layer. CONSTITUTION: A second electrode(103) is separately located on a first electrode(101). An organic light emitting layer(102) is located between the first electrode and the second electrode and is connected to the first electrode and the second electrode. A first pattern layer is located between the second electrode and an air layer and includes a plurality of first protrusions of a nanometer which are irregularly arranged. A glass substrate(104) is located on the second electrode. [Reference numerals] (105) Adhesive layer; (106) Film layer; (AA) Light extraction</p> |
