To show an image with minimal sense of discomfort felt by an occupant without quickening an updating cycle of an on-screen image, a virtual data generator making up a vehicle meter indicator device generates virtual data based on an arbitrary engine rotation speed between an engine rotation speed proportional to an image currently shown on a liquid crystal display device and a latest engine rotation speed rather than display data based on the latest engine rotation speed immediately before updating if the engine rotation speed declines. This allows the liquid crystal display device to show the generated virtual data on a liquid crystal panel as a virtual image for updating.
