The first vertical connection line DV1′, the second vertical connection line DV2′, and the third vertical connection line DV3′ may not be electrically connected to the data lines or the horizontal connection lines. Therefore, the first vertical connection line DV1′, the second vertical connection line DV2′, and the third vertical connection line DV3′ respectively intersecting the first horizontal connection line DH1, the second horizontal connection line DH2, and the third horizontal connection line DH3 may be omitted. However, the first vertical connection line DV1′ passes the pixels through which the second data line DL2 passes, the second vertical connection line DV2′ passes the pixels through which the fourth data line DL4 passes, and the third vertical connection line DV3′ passes the pixels through which the sixth data line DL6 passes such that the pixels through which the first data line DL1 and the first additional vertical connection line DV1 pass, the pixels through which the third data line DL3 and the second additional vertical connection line DV2 pass, and the pixels through which the fifth data line DL5 and the third additional vertical connection line DV3 pass may have substantially identical or similar structures to those of the pixels through which the second data line DL2, the fourth data line DL4, and the sixth data line DL6 pass. As such, the display apparatus capable of displaying high-quality images may be implemented.
