A passivation layer covers a portion of the first conductive line. A second conductive line is positioned between the display area and the first conductive line, overlapping the first connection line and including a hole. The hole of the second conductive line overlaps one of at least one opening. A passivation layer is interposed between the second conductive line and a first connection line. Overlapping areas between the first and second conductive lines outside of the display area are decreased, and thus, an occurrence of a short circuit in the display apparatus is decreased. ## Claims ### Claim 1 A display apparatus comprising: a substrate comprising a display area;
