A display-driver data line driving device includes a multichannel shift resistor and divided data lines to accommodate a display panel with various levels of resolution and reduce power consumption. The data line driving device includes a first display latch portion (L1 to L6) latching data supplied via a divided data line DL1 with a shift pulse outputted from a first shift resistor (S1 to S6), a second display latch portion (L7 to L12) latching data supplied via a divided data line DL2 with a shift pulse outputted from a second shift resistor (S7 to S12), a third shift resistor 21 sending a shift pulse shifted by the first shift resistor to the second shift resistor, and selector circuits changing a channel between the first shift resistor and the third shift resistor 21 and a channel between the third shift resistor 21 and the second shift resistor. The third shift resistor is used to control the start and stop of the drive of the data lines.
