A gray scale display driving method of a matrix liquid crystal display (LCD) and a display driver implementing this method, can reduce the scanning and data electrode driving signal voltages and the driving voltage magnitude variation for the respective sub-frames and can improve the picture quality. The method includes the steps of determining an n-bit error-diffused value of N-bit picture data, where n is smaller than N, converting the N-bit picture data into an M-bit code, where M is larger than or equal to N, error-diffusing n-bits of the converted picture data, and displaying picture data of M-n bits, with n bits being error-diffused, as a picture by a gray display method.
