Abstract: A display device includes a display unit that includes first pixels and second pixels alternately arranged in each of a first column and a third column, and third pixels arranged in a second column between the first column and the third column, wherein the first pixels and second pixels are alternately arranged in the third column in an order reverse to that of the first column. The display device includes a test unit in which first and second switches are coupled to columns including first pixels and second pixels alternatingly arranged. The first and second switches are spaced apart to prevent simultaneous damage from electrostatic discharge.
