摘要： PROBLEM TO BE SOLVED: To reduce power consumption and to improve picture quality of a liquid crystal display device. SOLUTION: The liquid crystal display device is provided with a liquid crystal panel in which liquid crystal cells that are formed for every region defined by the crossing of gate lines and data lines, are connected to mutually different data lines, that are alternating and made adjacent in i (i is a positive number) horizontal line units, through thin film transistors, gate drivers which drive the gate lines, a multiplexer array which selects an output channel for inputted pixel data or the like in response to the control signals that are polarity reversed in an i horizontal interval unit and adds one blank data and a data driver which drives the data lines or the like including a digital analog converter array that converts the pixel data or the like and blank data and the pixel data, whose polarities are reversed in the data line unit and the polarities are reversed in a frame unit, into blank signals.
