Referring to FIG. 10B, neighboring data lines of the data lines DLa and DLb of the first group and the second group may be located on different layers. For example, one of neighboring data lines DLa of the first group may be located on the second interlayer insulating layer 2150, and the remaining one of the neighboring data lines DLa of the first group may be located on a third interlayer insulating layer 2160. Likewise, one of neighboring data lines DLb of the second group may be located on the second interlayer insulating layer 2150, and the remaining one may be located on the third interlayer insulating layer 2160. Alternatively, one of neighboring data lines DLb of the second group may be located on the first interlayer insulating layer 2143, and the remaining one may be located on the second interlayer insulating layer 2150. Likewise, neighboring data lines DLc of the third group may be located on different layers with an insulating layer therebetween.
Although the third interlayer insulating layer 2160 is further provided in FIG. 10B when compared to FIG. 10A, in another embodiment, one of neighboring data lines DLa of the first group may be located on the first interlayer insulating layer 2143, and the remaining one may be located on the second interlayer insulating layer 2150.
