1. A display device comprising:
a display panel comprising a display area which has a flat portion and a bending portion; and
a color compensation part configured to compensate for input data signals by applying data gains which are set differently for the flat portion or the bending portion,
wherein the data gains for the bending portion change to rise from an outermost part of the bending portion to a boundary between the bending portion and the flat portion,
wherein a first data gain for the outermost part of the bending portion is set to be greater than 0 and less than 1, and is set differently for each color of the input data signals,
wherein a second data gain for the boundary is fixed to 1 regardless of colors of the input data signals,
wherein the first data gain includes an adaptive threshold gain, the adaptive threshold gain varying between a highest threshold gain and a lowest threshold gain, the highest threshold gain having a value greater than the adaptive threshold gain and the lowest threshold gain having a value lower than the adaptive threshold gain,
wherein the adaptive threshold gain is a reference value for evening out at least one of color deviations and color temperature differences between the flat portion and the bending portion,
wherein the adaptive threshold gain varies between the highest threshold gain and the lowest threshold gain based on external input information.
