PROBLEM TO BE SOLVED: To enable a driver to always grasp a driving state at current time.SOLUTION: In an on-vehicle display system, a margin deriving unit derives a margin that is a parameter according to a state of a driver at present time, and a risk deriving unit derives a risk that is a parameter according to a degree of risk of an accident at the present time. A display always displays thereon a driving state mark 4 that is a guidance graphic according to the margin and the risk while the driver is driving a vehicle. Therefore, the driver can always grasp the state of the driver himself/herself and the degree of risk of the accident at the present time.
