The present invention provides a light emitting device. In the present invention, a magnetic material is added to the light emitting device to change the current path and the distribution of the current density. As the main distribution of the current density is moved from the area between the electrodes to the area under light-out plane, the emitted light is no longer blocked by the electrodes, such that the light emitting efficiency can be enhanced and the distribution of the current density remains homogeneous.
