Abstract: A display device is provided. The display device comprises a plurality of data lines extending in a first direction. The display device also comprises a plurality of gate lines. The plurality of gate lines comprises a first gate line, a second gate line and a third gate line extending in a second direction different than the first direction to form a matrix with the plurality of data lines. The first gate line and the second gate line are separated from each other and are arranged in a same row of the matrix. The display device further comprises a first gate connector line and a second gate connector line, respectively, electrically connecting the first gate line and the second gate line to one or two gate drivers. The first gate connector line and the second gate connector line extend in the first direction.
