Abstract
A display apparatus includes a first power supply voltage line in a non-display area and including a first conductive layer, a first organic layer on the first conductive layer, and a second conductive layer on the first organic layer, a second power supply voltage line in the non-display area and including a third conductive layer spaced apart from the first conductive layer, and a fourth conductive layer on the first organic layer which is on the third conductive layer, a first dam portion adjacent to the first power supply voltage line, a second dam portion adjacent to the first dam portion, and a third dam portion between the first power supply voltage line and the first dam portion. The fourth conductive layer includes an opening exposing an upper surface of the first organic layer between the first power supply voltage line and the second dam portion.
