Abstract:
A display apparatus includes: a substrate having a display area and a peripheral area outside the display area; a first conductive layer on the substrate in the peripheral area and comprising a first hole; a second conductive layer on the first conductive layer and overlapping the first conductive layer, the second conductive layer comprising a second hole; a planarization layer extending from the display area to the peripheral area and comprising at least two organic insulating layers between the first conductive layer and the second conductive layer; and a display element on the planarization layer in the display area, wherein a part of a portion of the second conductive layer except for the second hole is in contact with a part of a portion of the first conductive layer except for the first hole.
