    Abstract: An organic light emitting diode display device includes a lower substrate, a plurality of lower electrodes, a light emitting layer, an upper electrode, and a first functional module. The lower substrate includes a first module region that includes sub-pixel regions and transmissive regions, and a display region that surrounds the first module region and includes the sub-pixel regions. The lower electrodes are respectively disposed on the lower substrate in the sub-pixel regions in the first module region. The light emitting layer is disposed on the lower electrodes, and includes a first opening between two adjacent lower electrodes. The upper electrode is disposed on the light emitting layer, and includes a second opening that overlaps the first opening. The first functional module is disposed on a bottom surface of the lower substrate in the first module region.

    Abstract: An apparatus for manufacturing a display device includes a mask assembly arranged inside a chamber and facing a display substrate, a magnetic force portion arranged inside the chamber and applying a magnetic force to the mask assembly, and a deposition source which is arranged inside the chamber, faces the mask assembly, and supplies a deposition material that passes through the mask assembly and is deposited on the display substrate. The mask assembly includes a first mask layer including a first mask opening, and a second mask layer disposed on the first mask layer. The second mask layer includes a metal layer including a metal opening corresponding to the first mask opening, and an inorganic layer including an inorganic opening corresponding to the first mask opening and the metal opening. In a plan view, a width of the metal opening is greater than a width of the inorganic opening.
