Abstract: A display device includes an active pattern disposed on a substrate, a first transistor, a first scan line, a first power voltage line, a first electrode pattern and an organic light-emitting layer disposed on the substrate. The first transistor includes a first gate electrode disposed in a first overlapping area of the active pattern where the first gate electrode overlaps the active pattern. The first scan line is disposed adjacent to the first gate electrode. The first power voltage line includes a first electrode portion and a second electrode portion. The first electrode portion overlaps the first gate electrode. The second electrode portion extends from the first electrode portion in a direction crossing the first scan line and overlaps the first scan line.

Abstract: An organic light-emitting display apparatus includes: a substrate; a pixel electrode above the substrate; an intermediate layer above the pixel electrode and comprising an organic emission layer; an opposite electrode above the intermediate layer; and an encapsulation structure above the opposite electrode and comprising at least one inorganic film and at least one organic film. A difference between a refractive index of the at least one inorganic film and a refractive index of the at least one organic film is in a range between about 0.3 to about 0.5. A thickness of the at least one inorganic film is in a range of about 0.7 μm to about 1.5 μm. A thickness of the at least one organic film is in a range of about 3.5 μm to about 6.5 μm.
