The light-emitting element is disposed in the partitioning wall opening. The partitioning wall includes a first partitioning wall layer disposed on the pixel defining film and defining a portion of a first area of the partitioning wall opening, a second partitioning wall layer disposed on the first partitioning wall layer and defining a portion of a second area of the partitioning wall opening.
