Abstract:
1. An organic electroluminescent display panel comprising: a substrate; a plurality of banks, each having a tapered shape of cross section comprised by a pair of side surfaces, an upper surface and a bottom surface respectively connected to the side surfaces, the banks being arranged on a top surface of the substrate in side-by-side relationship at an interval; a first electrode layer covering the top surface of the substrate between the banks and the side surfaces of the banks adjacent to such top surface; a pair of insulating layers coating a portion of the first electrode layer, said portion covering the side surfaces of the banks, each of the insulating layers having one end on a respective bank; an organic layer laminated on the insulating layer and the first electrode layer, the organic layer having two ends which are disposed on the banks; a second electrode layer laminated on the organic layer, the second electrode layer having two ends which are disposed on the banks; and a plurality of walls, each standing on the upper surface of the banks; wherein the walls have an upper surface wider than a lower surface; and wherein said two ends of the second electrode layer and the organic layer are positioned so as not to cover said one end of the respective insulating layer.
