Abstract: A display device including a substrate and a plurality of pixels in a display region of the substrate. Each of the pixels includes first and second sub-pixels, and each of the first and second sub-pixels has a light emitting region for emitting light. The first sub-pixel includes a first light emitting element in the light emitting region and configured to emit visible light. The second sub-pixel includes a second light emitting element in the light emitting region and configured to emit infrared light and a light receiving element configured to receive the infrared light emitted from the second light emitting element to detect a user's touch. The second light emitting element and the light receiving element in the second sub-pixel are electrically insulated from and optically coupled to each other to form a photo-coupler.

Abstract: Provided is a mask having a plurality of cell areas, each of which has a plurality of through-portions defined therein. The mask includes a mask film including a polymer and a conductive layer disposed on at least one surface of the mask film and including conductive metal or a conductive metal oxide. Accordingly, precision of a deposition process is enhanced while reducing process time and costs in a manufacturing process of the mask, and thus the yield in manufacturing a display panel using the mask is improved. Therefore, the display panel manufactured using the mask may have improved reliability.
