A color correction circuit, a driving device, and a display device are provided to convert numerical values of R, G, and B by using a matrix operation circuit in order to adjust the color tone of an image displayed on a device so as to execute a color display based on the brightness of each of the R, G, and B. A color correction circuit includes a pre-gamma circuit(410), a matrix operation circuit(110) and a post-gamma circuit(430). The pre-gamma circuit converts input numerical values of R, G, and B(Red, Green, Blue) into linear data. The matrix operation circuit performs an operation by using numerical values from the pre-gamma circuit. The post-gamma circuit converts numerical values from the matrix operation circuit into nonlinear data. A number of bits of the numerical values from the pre-gamma circuit become greater than a number of bits of the input numerical values of each of the R, G, and B to increase resolution. The color correction circuit has average color correction coefficients for the display device and fine adjustment coefficients for finely adjusting a color variation of each display device. In addition, the color correction circuit has operation coefficients for the matrix operation circuit are obtained by adding the average color correction coefficients and the fine adjustment coefficients.
