A display panel is adapted to display at least one meter image including a pointer image constituting a pointer and a mark image constituting a mark that the pointer is adapted to point to. A processor controls the display state of the pointer image. The processor causes the pointer image to be displayed on the display panel when the pointer image does not point to the mark image and causes the pointer image to be displayed on the display panel in a second display mode when the pointer image points to the mark image. The first display mode and the second display mode are different.
