发明名称 Display unit having insulating film with tapered portions
摘要 A display unit capable of preventing breaking of a second electrode and decreasing a leakage current through an organic layer is provided. The display unit includes a plurality of organic light emitting devices over a flat substrate. Each of the plurality of organic light emitting devices has a first electrode, an insulating film having an aperture correspondingly to the first electrode, an organic layer formed at least on the first electrode in the aperture and composed of a plurality of layers including a light emitting layer, and a second electrode sequentially. The insulating film has a low taper section having a tilt angle formed by a side face of the aperture and a flat face of the substrate that is smaller than a tilt angle of the other section of a circumference of the aperture in part of the circumference of the aperture.
