A display device is provided with a display panel; first to n-th cascade-connected drivers (n being an integer of two or more); a controller transmitting compressed image data to the first driver. The i-th driver of the first to n-th drivers includes a drive circuitry driving the display panel; a first bus adapted to data transfer to the (i+1)-th driver of the first to n-th drivers; a second bus adapted to data transfer to the driver circuitry; and a decompression section receiving the compressed image data from the (i−1)-th driver of the first to n-th drivers or the controller. The decompression section of the i-th driver transfers the received compressed image data to the (i+1)-th driver through the first bus thereof, when the received compressed image data are not associated with the i-th driver. When the received compressed image data are associated with the i-th driver, the decompression section of the i-th driver decompresses the received compressed image data to generate decompressed image data and feeds the decompressed image data to the drive circuitry through the second bus. The drive circuitry drives the display panel in response to the decompressed image data.
