摘要： A display device includes a substrate, a pixel area, and a plurality of data lines. The substrate includes display and non-display areas. The pixel area is in the display area and includes a first pixel column and a second pixel column. The pixels in the first and second columns emit light of different colors. The data lines are respectively coupled to the first pixel column and the second pixel column. In the non-display area, a data line is coupled to one of the first or second pixel columns corresponding to a color on which influence of a resistance is greater than on another color. The data lines has a line or contact structure with a resistance less than a resistance of a line or contact structure of a remaining data line coupled to a remaining pixel column.
