Abstract
To provide an organic electroluminescent device and a method of manufacturing the same, in which the organic electroluminescent device has an organic functional layer formed by a liquid phase method, the organic functional layer formed in a uniform thickness while maintaining an aperture ratio, thereby obtaining a uniform and high efficient emission. According to an organic EL device of the present invention, an organic EL element having an organic functional layer interposed between a pixel electrode and a common electrode is arranged on a substrate, and the organic functional layer is arranged in a region surrounded by a bank arranged along the periphery of the pixel electrode, and-at the same time, a hole injection layer and a light-emitting layer are stacked at the pixel electrode. A convex portion protruded at the hole injection layer is arranged on the pixel electrode and a part of the hole injection layer is interposed between the convex portion and the light-emitting layer.
