ABSTRACT:
An organic electroluminescent device includes an element substrate including a plurality of light-emitting elements, each including a pair of electrodes with an organic luminescent layer therebetween, and a coating layer covering the light-emitting elements. A sealing substrate is opposed to the element substrate. The sealing substrate includes a plurality of color layers and a light-shielding layer separating the color layers from each other. An outer region sealing layer bonds the outer region of the sealing substrate to the outer region of the element substrate. A filling layer is surrounded by the outer region sealing layer, and bonds the sealing substrate and the element substrate together in the region in which the light-emitting elements and the color layers are arranged. The color layers and the light-shielding layer of the sealing substrate are covered with a surface-modifying layer made of a material having a higher surface energy to the material of the filling layer than the surface energy to the surfaces of the color layers and light-shielding layer.
