    Abstract: An electroluminescent display device includes a display panel in which a plurality of pixels are disposed, each pixel including a first sub pixel, a second sub pixel, a third sub pixel, and a fourth sub pixel each having a different color; a data driver which supplies a data voltage to the plurality of pixels by means of a plurality of data lines; and a gate driver which supplies a gate signal to the plurality of pixels by means of a plurality of gate lines. Each of the plurality of data lines is divided into a plurality of sub data lines, and each of the plurality of sub data lines is connected to a plurality of sub pixels having the same color, the sub pixel includes a switching transistor, and a source electrode of the switching transistor includes a compensation pattern which is provided on at least one side of the source electrode spaced apart from the gate line, thereby improving luminance difference between sub pixels having the same color which are converted by the exposure overlay shift of the gate line.
