Abstract:
A display apparatus includes: a plurality of pixels on a substrate and each comprising a first electrode, an intermediate layer, and a second electrode, the intermediate layer comprising an emission layer; a display area comprising the plurality of pixels; a first conductive layer outside the display area; a first planarization layer comprising a first contact hole exposing an upper surface of the first conductive layer, and a second contact hole between the display area and the first contact hole; a second conductive layer connected to the first conductive layer through the first contact hole; a second planarization layer on the first planarization layer and comprising a third contact hole formed at a position overlapping the second contact hole; and a connection layer directly contacting the second conductive layer at a position where the second contact hole and the third contact hole overlap each other.
