Abstract
An organic EL element including: pixel electrode on a section of TFT substrate corresponding to pixel region; auxiliary connector on a section of TFT substrate corresponding to auxiliary region; hole injection layer on pixel electrode and auxiliary connector; and light-emitting layer on a section of hole injection layer corresponding to pixel region. The organic EL element additionally includes: electron injection layer on light-emitting layer and a section of hole injection layer corresponding to auxiliary region; and seamless common electrode on electron injection layer. Hole injection layer contains WOx. Electron injection layer contains NaF. Common electrode contains Al that causes the reduction of NaF contained in electron injection layer.
