Abstract: A mask frame assembly manufactured via an extension-welding process on a stage, the mask frame assembly includes: a mask frame disposed on a stage, the mask frame including a first frame and a second frame having a first length, and a third frame and a fourth frame having a second length, the second length less than the first length. The mask frame assembly also includes a mask having respective ends welded and combined onto the first frame and the second frame. The first frame and the second frame include a slot disposed toward the stage, and at least portions of the first frame and the second frame corresponding to the slot are not in contact with the stage. The third frame and the fourth frame and the stage are in contact with the stage.

Abstract: A display device including a substrate in which at least one hole area is disposed. The substrate includes an active area. The display device also includes a thin film encapsulation (TFE) layer disposed on the substrate. A pixel including a plurality of sub-pixels is disposed on the active area. A plurality of first and second pixel groups each include the sub-pixels. The first and second pixel groups are disposed along a plurality of first and second lines of the active area, respectively. The first and second lines are alternated in the active area. A first deposition portion forming the common layer or the common electrode is disposed in the first pixel groups disposed along the first lines of the active area. A second deposition portion forming the common layer or the common electrode is disposed in the second pixel groups disposed along the second lines of the active area.
