Patent ID: 8552641

Claim:
An organic electroluminescence display panel having a display region and an outside region in contact with and surrounding the display region, the organic electroluminescence display panel comprising: a glass substrate extending in the display region and the outside region and having a flat glass substrate surface; a pixel circuit located in the display region and disposed on and projecting away from the flat glass substrate surface to terminate at a pixel circuit height, the pixel circuit fabricated from at least four different pixel circuit materials; a first protrusion located in the outside region, juxtaposed the pixel circuit and disposed on and projecting away from the flat glass substrate at approximately the pixel circuit height, the first protrusion fabricated from the at least four different pixel circuit materials and configured differently than the pixel circuit as viewed in cross-section; a single-compound flattening film contacting and at least substantially covering the pixel circuit and contacting and completely covering the first protrusion, the flattening film terminating in a flat flattening film surface disposed above the pixel circuit and the first protrusion; an organic EL thin film located in the display region and disposed on and projecting, in part, into the flattening film at a projection distance sufficient to contact the pixel circuit and projecting, in part, away from the flat flattening film surface to terminate at an organic EL thin film height, the organic EL thin film fabricated from at least two organic EL thin film materials; a second protrusion located in the outside region, juxtaposed and electrically insulated from the organic EL thin film and disposed on and projecting away from the flat flattening film surface at approximately the organic EL thin film height, the second protrusion fabricated from the at least two organic EL thin film materials and configured differently than the organic EL thin film as viewed in cross-section; a single-compound, thermally-hardened or photo-set sealing material contacting and covering the organic EL thin film circuit and the second protrusion and terminating in a flat sealing material surface disposed above the organic EL thin film circuit and the second protrusion; and a glass plate disposed on the flat sealing material surface and over the organic EL thin film circuit and the second protrusion, wherein the first and second protrusions have similar shapes as viewed in cross-section and the second protrusion is stacked on top of the first protrusion and is separated therefrom by the flattening film.
