  • Publication number: 20190305066
    Abstract: Included are first light-emitting element including a first organic layer having an island shape, and a first lower electrode, an electrode cover film having an insulating property and covering an edge of the first lower electrode, and a second light-emitting element including a second organic layer that has an island shape and that is an identical layer to the first organic layer, and a second lower electrode. As an opening of the electrode cover film wholly overlaps with the first lower electrode and the first organic layer, so that the opening defines a light-emitting region of the first light-emitting elements. When the edge of the second organic layer overlaps with the second lower electrode without being interposed with an insulating film, the edge of the second organic layer defines a light-emitting region of the second light-emitting element.

  • Patent number: 10196737
    Abstract: On a vapor deposition target surface of a vapor deposition target substrate placed on a substrate tray in a vapor deposition device, display regions on which vapor deposition particles are to be deposited are arranged in alignment to be apart from each other in a direction parallel with a scanning direction, and the substrate tray includes a blocking part configured to block the vapor deposition particles to be deposited onto regions adjacent to the display regions in a direction parallel with the scanning direction. This prevents a degree of freedom in designing of the vapor deposition target substrate from being restricted even in performing scan vapor deposition.
