As shown in FIG. 23, among the first to third horizontal connection lines DH1 to DH3, the first horizontal connection line DH1 may be the longest, and the third horizontal connection line DH3 may be the shortest. Therefore, the third vertical connection line DV3′ and the third additional vertical connection line DV3 electrically connected to the longest first horizontal connection line DH1 may have the smallest lengths, and the first vertical connection line DV1′ and the first additional vertical connection line DV1 electrically connected to the shortest third horizontal connection line DH3 may have the greatest lengths. Thus, connecting lengths of the sixth data line DL6 and the sixth input line IL6, connecting lengths of the fourth data line DL4 and the fourth input line IL4, and connecting lengths of the second data line DL2 and the second input line IL2 may be substantially identical or similar to one another. As such, distortion of the data signals due to voltage drop that is generated as the connecting lengths vary may be reduced.
