The data wiring 1810 may extend in the second direction (or y-axis direction). The data wiring 1810 may correspond to the data line DL of FIG. 6. The data wiring 1810 is electrically connected to the seventh transfer wiring 1720 via a contact hole 1810CNT, and the data signal Dm from the data wiring 1810 may be transferred to the first semiconductor layer 1100 via the seventh transfer wiring 1720 and the second transfer wiring 1620 and then may be applied to the switching transistor T2. The data wiring 1810 may include one of the first to sixth data lines DL1 to DL6 described above with reference to FIG. 5.
The vertical connection wiring 1820 may extend in the second direction (or y-axis direction). The vertical connection wiring 1820 may include one of the first to third vertical connection lines DV1′ to DV3′, the first to third additional vertical connection lines DV1 to DV3, the first to third auxiliary vertical connection lines ADV1′ to ADV3′, and the first to third additional auxiliary vertical connection lines ADV1 to ADV3 described above with reference to FIG. 5, according to the location of the pixel. For example, the third connecting electrode layer 1800 may include a vertical connection line, an additional vertical connection line, an auxiliary vertical connection line, and/or an additional auxiliary vertical connection line.
