摘要： A display wiring line provided on a resin substrate layer, a flattening film covering the display wiring line, and an organic EL element provided on the flattening film are provided. The display wiring line includes first to third conductive layers layered sequentially from the resin substrate layer side. In the display wiring line, the second conductive layer is formed with a width smaller than a width of each of the first conductive layer and the third conductive layer, and a portion of a perimeter edge surface corresponding to the second conductive layer includes a recessed portion, and a resin cover covering a perimeter edge surface of the second conductive layer is provided in the recessed portion in a portion of the display wiring line exposed from the flattening film.

摘要： In an organic EL display device, a taper angle of a separation layer surrounding edges of an organic EL layer disposed in each pixel and being disposed between adjacent pixels is different from a taper angle of a frame-shaped bank surrounding edges of an organic layer. As a result, qualities required for layers surrounded by the separation layer and the frame-shaped bank respectively are satisfied.

摘要： A method of manufacturing a display device includes a step of forming a first inorganic film constituting a sealing film and a step of forming an organic film constituting the sealing film. Between these steps, the method further includes a foreign matter inspection step of inspecting a substrate surface on which the first inorganic film has been formed and identifying the location of a foreign matter adhering to the substrate surface, and a partial ejection step of using an ink-jet method to eject ink to be formed a part of the organic film at the location of the foreign matter on the substrate surface identified in the foreign matter inspection step.
