Abstract:
1. An organic display module including a current supply line; a thin film transistor connected to the current supply line; a first electrode connected to the thin film transistor; an interlayer insulation layer provided on the first electrode, and having an aperture to expose at least a portion of the first electrode; an organic light emitting layer provided on the first electrode through the aperture; a second electrode covering the organic light emitting layer; and a passivation film covering the second electrode, wherein a surface of the passivation film has a higher degree of flatness than the second electrode, wherein the interlayer insulation layer includes a portion forming an inner wall of the aperture, said portion of the interlayer insulation layer having a taper to decrease in thickness in a direction from a top portion of the aperture toward a bottom portion of the aperture, the inner wall of the aperture being located between the organic light emitting layer and the first electrode layer; wherein, to form the surface with the higher degree of flatness of the passivation film compared with the degree of flatness of the second electrode, a thickness of the passivation film which is formed over the organic light emitting layer in the aperture is formed to be thicker than a thickness of the passivation film which is formed over the interlayer insulation layer.
