Abstract: According to one embodiment, a manufacturing method of a display device includes forming a lower electrode, forming an organic layer on the lower electrode, and forming an upper electrode on the organic layer. The forming the organic layer includes a process of forming a first blocking layer, a process of forming a first light emitting layer on the first blocking layer, and a process of forming a second blocking layer on the first light emitting layer. A spread angle of a material for forming the first light emitting layer is less than a spread angle of a material for forming the first blocking layer. A spread angle of a material for forming the second blocking layer is greater than the spread angle of the material for forming the first light emitting layer.

Abstract: A touchscreen includes an OLED, upper-layer inorganic films on the OLED, a lower-layer inorganic film stacked between the OLED and a substrate, and a touch sensor on the upper-layer inorganic film. The upper-layer inorganic films and the lower-layer inorganic film extend over a display area and a picture-frame area. A lower-layer wiring is formed of a conductive film stacked between the OLED and the substrate. A sensor wiring is formed of a conductive film on the upper-layer inorganic film. An inorganic film joining portion where the upper-layer inorganic films and the lower-layer inorganic film are directly joined together or joined together with another inorganic material interposed therebetween is provided in the picture-frame area. A contact portion that electrically connects the sensor wiring with the lower-layer wiring is provided, in a plan view, in the inorganic film joining portion or an area on the outside thereof.
