Organic EL display apparatus and method of manufacturing organic EL display apparatus

An organic electro luminescent (EL) display apparatus comprising:

• a substrate having a surface on which a drive circuit comprising a thin film transistor is formed,
• a planarizing layer including a first inorganic insulating layer and an organic insulating layer to planarize the surface of the substrate by covering the drive circuit, and
• an organic light emitting element, the organic light emitting element comprising a first electrode being formed on a surface of the planarizing layer and connected, via a contact formed in the planarizing layer, to the drive circuit, an organic light emitting layer being formed on the first electrode, and a second electrode being formed on the organic light emitting layer,
• wherein a surface of the organic insulating layer is formed such that a planarity thereof is brought to be greater than or equal to 20 nm and less than or equal to 50 nm in arithmetic average roughness Ra, and
• wherein the first electrode is formed on only a region of the surface of the planarizing layer, in which the contact is not formed, and the organic light emitting layer is formed on only the first electrode, and the first electrode and the organic light emitting layer have substantially the same degree of surface roughness as a surface roughness of the planarizing layer, thereby, even in a microscopically planar state, a surface of the organic light emitting layer having no unevenness.
