PROBLEM TO BE SOLVED: To provide an information display device, from which the troublesomeness to be felt by a user is reduced.SOLUTION: In information displaying processing to be executed by a control device of an information display device, there is identified a user's depth of field estimated from the pupil diameter of a driver (at S150). If the gazing distance is contained within the range of the identified user's depth of field (S160: YES), a virtual image VI_1 indicating necessary display information is formed as that the eyes of the driver are focused on the virtual image VI_1. Unless the gazing distance is not contained within the range of the user's depth of field (S160: NO), the eyes of the driver are not focused on the virtual image VI_1, so that a virtual image VI_2 indicating the necessary display information is formed at a position not overlying the virtual image VI_1. |
