To efficiently lay out an integrated driving device mounted on a panel of a display apparatus.

The integrated driving device is lengthy and mounted on peripheral parts of the display apparatus provided with a display part on a panel substrate, and includes a logic part 120, a power supply circuit part 110, and DA converter 180. The logic part 120 includes a digital display data processing part and a timing signal creating part for creating a timing signal necessary for the display apparatus, and the digital-analog converter 180 converts digital display data obtained by the digital display data processing part into analog data. The power supply circuit part 110 generates power supply voltage used for the display apparatus using the signal from the timing signal creating part. In the longitudinal direction of such a lengthy form integrated driving device, the power supply circuit 110 and the DA converter 180 are arranged with the logic part 120 in-between so as to be located adjacent to the logic part 120.
