Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a flat board display device, in which the constitution of a control board is facilitated and the manufacturing cost is reduced by sharply reducing the number of transfer lines, while constituting the device so that gradation voltages generated in a controller are transferred to a column drive integrated circuit as gamma data and the circuit outputs column signals to a liquid crystal panel. SOLUTION: The signal-processing part 21 of a controller 20 receives driving data and a drive control signal and outputs R, G, B data, by controlling timing formats of the driving data. A gamma data generating part 22 generates and outputs gamma data, in which the driving data are digitized for every gradation in order to express respectively plural gradation by referring to a reference voltage to be applied from a power source part 16. Then, the R, G, B data and the gamma data which are transferred from the controller 20 and column signals which are generated in a column drive integrated circuit 14 as column driving control signals are supplied to a liquid crystal panel 10.
