A video display device includes a display panel; a memory storing defect information for compensating data to be displayed on defect regions of the display panel; a compensation circuit comprising a first compensator that compensates the data to be displayed on the defect regions using the defect information from the memory, and a second compensator that finely compensates the data compensated by the first compensator using a first dither pattern, the compensation circuit supplying data to be displayed on normal regions without compensation; a timing controller comprising a dithering unit for finely compensating data output from the compensation circuit, using a second dither pattern having a size larger that a size of the first dither pattern; and a panel driver for driving the display panel under a control of the timing controller.
