A display device includes a first substrate; a plurality of gate lines arranged in a row direction on the first substrate; a plurality of data lines arranged in a column direction intersecting the row direction; and a plurality of pixels formed in a plurality of pixel areas defined by the gate and data lines, the plurality of pixels comprising at least a first pixel and a second pixel respectively disposed in a first pixel area and a second pixel area that are immediately adjacent to each other. Each of the first and second pixels comprises a thin film transistor electrically connected to the gate and data lines, and a pixel electrode electrically connected to the thin film transistor. The data lines are disposed-apart by different distances from each other in the column direction. Each of the first and second pixel areas comprises a first edge portion adjacent to one of the gate lines and a second edge portion adjacent to another of the gate lines, a length of the first edge portion being greater than a length of the second edge portion. The thin film transistor is disposed at the first edge portion of the first and second pixel areas.
