A liquid-crystal display device, including: a first data line and a second data line each lengthwise extended in a first direction and spaced apart from each other, a gate line lengthwise extended in a second direction different from the first direction, the gate line defining: a first region thereof overlapping the first data line, a second region thereof overlapping the second data line and a third region thereof extended between the first region and the second region, and a pixel including a switching element, a first electrode of the switching element being connected to the first data line and a second electrode of the switching element overlapping each of the first to third regions. In the first direction, a width of the third region is smaller than a width of each of the first and second regions.
