17. An organic light-emitting display apparatus fabricated using a mask assembly for thin film deposition, the organic light-emitting display apparatus comprising:
-
a display substrate; a thin film transistor disposed on the display substrate; an organic light-emitting device comprising; a first electrode electrically connected to the thin film transistor and disposed on each sub-pixel of the display substrate; and an intermediate layer comprising a light emissive layer disposed on the first electrode, and a second electrode disposed on the intermediate layer; and an encapsulation substrate covering the organic light-emitting device, wherein; a pattern of the sub-pixel comprises at least one first deposition pattern that extends in one direction of the display substrate and a plurality of second deposition patterns disposed on both sides of the first deposition pattern with respect to the first deposition pattern; and the first deposition pattern and the second deposition patterns are repeatedly arranged in the other direction of the display substrate. - View Dependent Claims (18, 19, 20)
