Abstract: A display apparatus includes: a plurality of transistors in a display area; a plurality of light-emitting diodes in the display area, and electrically connected to the plurality of transistors; a power voltage supply line in a peripheral area outside the display area; a partition wall in the peripheral area, and overlapping with a part of the power voltage supply line; and an encapsulation layer on the plurality of light-emitting diodes. The power voltage supply line has a multi-layered structure including: a first conductive layer; a second conductive layer on the first conductive layer; and a third conductive layer on the second conductive layer. A side shape of a first portion of the power voltage supply line that does not overlap with the partition wall is different from a side shape of a second portion of the power voltage supply line overlapping with the partition wall.
