Embodiment approach
[0078] In this regard, according to an exemplary embodiment of the present invention, magnetic materials included in the electrodes have the same magnetization direction (or rotation direction). When the magnetic material included in the electrodes is magnetized in the same direction, only charges having a rotation direction corresponding to the magnetization direction can be injected into the light emitting layer. By using the electrode including the magnetic material, the present invention can control the rotation direction of charges injected into the light emitting layer, thereby possibly improving the light emission efficiency of the organic light emitting device.
[0079] In particular, when the magnetization direction of the magnetic material included in the electrode, that is, the rotation direction is an upward direction, charges with an upward rotation direction pass through the electrode without being blocked, but charges with a downward rotation direction are blocke...
