1. A display device, comprising:
a display panel including a plurality of pixels respectively connected to a corresponding data line of a plurality of data lines and a corresponding scan line of a plurality of scan lines; and
a test circuit electrically connected to the data lines, and
wherein the display panel includes a first area having a first light transmittance and a second area having a second light transmittance,
wherein the plurality of pixels includes a first pixel disposed in the first area and a second pixel disposed in the second area,
wherein the test circuit provides a first test data signal to a data line connected to the first pixel among the plurality of data lines in a bias frame, and provides a second test data signal to a data line connected to the second pixel among the plurality of data lines in the bias frame,
wherein a voltage level of the first test data signal is different from a voltage level of the second test data signal during the bias frame such that a luminance change of the display device has a curved shape in the bias frame similar to that of a driving frame, and
wherein the driving frame and the bias frame are alternately repeated in a single frame.
