PROBLEM TO BE SOLVED: To save power consumption and simplify a circuit structure of a data line driving device by collecting and reusing electric charge of a data line in a matrix display panel. SOLUTION: A data line driving device is provided with a matrix display panel provided with a plurality of data lines DL, a data line driving circuit 1A provided with a plurality of switch units QP1i, QN1i (i=1-N: the same in the following) individually put between a data voltage impression terminal P12 and the respective data lines, electric charge accumulating means C11, L11 which are connected to the data line driving circuit 1A and accumulate electric charges on the data lines, and an electric charge collecting switch QS1i provided with a parasitic diode DS1i arranged between the data line driving circuit 1A and the respective data lines. Conduction of the electric charge collecting switch QS1i is accomplished when the electric charges on the data line are collected to the electric charge collecting means C11, L11. |
