A display control device includes a hardware processor. The hardware processor implements functions of a first operating system, a second operating system, and a hypervisor. The first operating system controls execution of at least one of a first application and a second application. The first application serves to generate a first content image to be displayed on a first display device mounted on a vehicle. The second application serves to generate a second content image to be displayed on a second display device mounted on the vehicle. The second operating system is different from the first operating system. The hypervisor controls execution of the first operating system and the second operating system.
