Abstract: A display device includes a pixel electrode, a pixel defining layer including an opening extending to a portion of the pixel electrode, a first auxiliary electrode on the portion of the pixel electrode to which the opening extends, a second auxiliary electrode on the first auxiliary electrode, an intermediate layer on the pixel defining layer and the second auxiliary electrode, and a common electrode on the intermediate layer. A side surface of the first auxiliary electrode is positioned inward of a side surface of the second auxiliary electrode within the opening of the pixel defining layer to form an undercut shape. A hole injection layer of the intermediate layer includes a first portion on a side surface of the pixel defining layer defining the opening of the pixel defining layer, and a second portion disconnected from the first portion and on the second auxiliary electrode.

Abstract: A method of manufacturing a deposition mask includes preparing a mask-target substrate which has one surface on which a sacrificed layer pattern is formed and comprises a cover area covered by the sacrificed layer pattern and a plurality of exposed areas exposed by the sacrificed layer pattern; forming holes in the exposed areas of the mask-target substrate by emitting laser toward the mask-target substrate; and removing the sacrificed layer pattern, wherein the sacrificed layer pattern has a higher reflectance with respect to the laser than a reflectance of the mask-target substrate.

Abstract: An electronic device may include a display panel displaying an image. The display panel may include: a substrate including a first display region and a second display region, which are adjacent to each other, and a non-display region surrounding at least one side of each of the first and second display regions; a plurality of first pixels provided in the first display region; and a plurality of second pixels provided in the second display region. The second display region may have a light transmittance higher than that of the first display region, and each of the first pixels may have a size different from that of each of the second pixels.
