Abstract: Layers on a resin substrate in a peripheral area include wires extending in a wiring direction, and an inorganic insulating layer. The inorganic insulating layer is formed on first regions under the plurality of respective wires and on second regions each positioned between the adjacent first regions. The inorganic insulating layer includes a first portion on each first region. The inorganic insulating layer includes a second portion on each second region. The first portion is continuous in the wiring direction. The second portion is formed in at least either one of the manners such that the second portion is formed while avoiding a part of the second region on which the second portion is disposed or that the second portion is formed thinner than the first portion, and is continuous to the first portion adjacent to the second portion.

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.
