A display panel and method of manufacturing a display panel. A plurality of contact holes penetrate through an interlayer insulation film and have wiring lines connecting first electrode plates and second electrode plates with a thin-film transistor layer. The first electrode plates and the second electrode plates each include at least one concavity. The at least one concavity included in each of the first and second electrode plates coincide with the plurality of contact holes. A total volume of the at least one concavity in any of the first electrode plates is larger than a total volume of the at least one concavity in any of the second electrode plates, while a volume of a portion of the first organic functional layer corresponding to any of the first electrode plates at least approximates a volume of the second organic functional layer corresponding to any of the second electrode plates. A portion of the first organic functional layer entered into the at least one concavity in any of the first electrode plates is larger than a portion of the second organic functional layer entered into the at least one concavity in any of the second electrode plates, so that in locations other than the at least one concavity in the first electrode plates and the second electrode plates, the first organic functional layer is thinner than the second organic functional layer.
