Claim:
1. A display device comprising: a first display driver configured to output gradation signals to source lines of a display panel based on display data; and a second display driver configured to output gradation signals to other source lines of the display panel, wherein the first and second display drivers are each configured to generate gray scale reference voltages for producing gradation signals corresponding to the display data, the gray scale reference voltages having different voltage levels from each other and each corresponding to respective values of the display data, the first display driver is configured to sequentially transmit the gray scale reference voltages generated by itself to the second display driver, and the second display driver is configured to execute calibration for making smaller an absolute value of difference between gray scale reference voltages generated by the first and second display drivers based on the sequentially transmitted gray scale reference voltages.
