LIQUID CRYSTAL DISPLAY DEVICE AND DATA LINE DRIVER

摘要

PROBLEM TO BE SOLVED: To realize excellent display while preventing deterioration of liquid crystal and suppressing a flicker, and to reduce a frame space as to a digital data line driver. SOLUTION: The data line driver is provided with: an input-side data cross part which switches and supplies 1st data to be outputted from a 1st channel to a 2nd channel and 2nd data to be outputted from the 2nd channel to the 1st channel according to a data switching signal; 1st and 2nd reference power source parts 15 and 16 which are connected to the 1st and 2nd channels, respectively, and have the positive and negative reference voltages of polarity inverted driving; a selector part 17 which selects specified reference voltage from the 1st or 2nd reference power source part according to the 1st or 2nd data; and an output-side data cross part which switches and outputs the 2nd data of the 1st channel outputted from the selector part to the 2nd channel and the 1st data of the 2nd channel to the 1st channel.
