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.
