1. An electroluminescent display device comprising:
a display panel including a plurality of pixels;
a storage circuit configured to store information on a leakage curve indicating a luminance change value of a target pixel according to a change of an input pixel value of a neighboring pixel, the plurality of pixels including the target pixel and the neighboring pixel;
a luminance compensation circuit configured to
receive a plurality of input pixel values corresponding to the plurality of pixels, and
generate a plurality of compensated pixel values respectively corresponding to the plurality of pixels by compensating for lateral leakage based on the leakage curve, the lateral leakage being caused by leakage currents through a common conduction layer of the plurality of pixels; and
a data driver configured to drive the plurality of pixels based on the plurality of compensated pixel values, respectively.
