To provide a vehicle-purpose display device that enables a display upon an off-time of an action command signal, and can suppress power consumption.SOLUTION: A vehicle-purpose display device 1, which displays information, comprises; a display unit 30; a driver device 20 that drives the display unit 30; and a microcomputer 10 that drives the display unit 30 via the driver device 20, and thereby displays the information on the display unit 30. The driver device 20 includes a first clock generation unit 21 that generates an internal clock CLK1 serving as an action clock of the driver device 20 when an ignition signal IGN is off. The microcomputer 10 includes a second clock generation unit 15 that generates a system clock CLK2 serving as an action clock of the microcomputer 10, generates a peripheral module clock CLK3 serving as an action clock of the driver device 20 when the ignition signal IGN is on, and then outputs the peripheral module clock to the driver device 20.SELECTED DRAWING: Figure 3
