Abstract: Provided is a display apparatus including: a display panel including a display area and a peripheral area; a printed circuit board attached to the peripheral area and including a ground portion and a test electrode spaced apart from the ground portion; a connector including a plurality of connector terminals connected to an external control apparatus and electrically connecting the printed circuit board and the external control apparatus to each other; and a cover layer arranged on the printed circuit board and covering at least a part of the printed circuit board. Accordingly, not only the display quality and reliability of the electric characteristics of the display apparatus are improved, but also a loss is reduced and a yield is improved during manufacturing processes.
