PROBLEM TO BE SOLVED: To provide a plane display device in which a display module is optimized and a circuit configuration is simplified. SOLUTION: In a system 30 by which data with respect to a screen for screen and control signals therefor are supplied thereto, a picture signal processing part 34 decides a timing format with respect to the data and generates the control signals with respect to the data, then the control signals are encoded into a swing reduction type differential signal system in an encoder 36 and are outputted. The decoding of the differential signal system is performed in a scanning drive integrated circuit 16 or a column drive integrated circuit 18. Moreover, a control board 20 is provided with a power source part 22 which generates voltages needed for respective parts and output them, a gradation generating part 24 which generates gradation voltages and output them and a gate voltage generating part 26 which generates gate ON/OFF voltages and outputs them.
