Claim:
1. An organic EL display module comprising: a current supply line; a thin film transistor connected to the current supply line and is formed on the substrate, wherein the thin film transistor includes a predetermined metal covered by a predetermined insulation layer having a contact hole exposing a part of the predetermined metal; a first electrode that covers the predetermined insulation layer and is connected to the predetermined metal through the contact hole; an interlayer insulation layer, provided on the first electrode and the predetermined insulation layer, having an aperture to expose at least a portion of the first electrode, and wherein the interlayer insulation layer covers all edge portions of the first electrode, an organic light emitting layer provided on the first electrode through the aperture and on the interlayer insulation layer; a second electrode covering the organic light emitting layer; and a passivation film covering the second electrode, wherein the predetermined metal, the first electrode, the interlayer insulation layer, the organic light emitting layer, and the contact hole overlap each other in a plan view, wherein a thickness of the passivation film which is formed directly above the organic light emitting layer in the aperture of the interlayer insulation layer is formed to be thicker than a thickness of the passivation film which is formed directly above the interlayer insulation layer, and wherein both of an upper surface of the passivation film and a bottom surface of the passivation film are made of a compound inorganic material of silicon and nitride.
