A display device includes a gamma adjustment circuit employing a method for adjusting red, green, blue (R, G, B) data of an image signal. The gamma adjustment circuit provides at least one look up table (LUT) to store gamma correction values, determines whether at least two kinds of color data from the R, G, B data require adjustment, searches for gamma correction values corresponding to the at least two kinds of color data from the R, G, B data requiring adjustment in the at least one LUT, and outputs the R, G, B data and the gamma correction values corresponding to the at least two kinds of color data from the R, G, B data requiring adjustment.
