Abstract: A display device includes a substrate on which pixels are defined, a pixel electrode disposed for each of the pixels on the substrate, a pixel defining layer disposed along a boundary of the pixels, the pixel defining layer including an opening exposing the pixel electrode, a light emitting layer disposed on the pixel electrode in the opening of the pixel defining layer, and a hole injection layer disposed between the pixel electrode and the light emitting layer. The hole injection layer includes an adhesion promoting layer disposed on the pixel electrode.

Abstract: An apparatus for measuring a deposition rate includes a light source unit in a deposition region between a deposition source and a substrate in a vacuum chamber, the light source unit emits a monochromatic light toward a deposition material released from the deposition source, a photosensor unit that measures at least one of light absorption, scattering, and emission in the deposition region when light emitted from the light source unit passes through the deposition region, and a multi-pass forming unit defining a multi-pass path between the light source unit and the photosensor unit.
