Abstract

PURPOSE:To always observe both information in a satisfactory state by dividing the display surface of a display element into plural display areas, and forming plural hologram patterns corresponding to the number of divisions of the display surface of the display element, on a luminous flux coupling element. CONSTITUTION:A display area of the display surface 22a of a display element 22 is divided into at least two or more areas, a hologram having hologram patterns 29, 30 of different focal distances corresponding to the number of its divisions is used as a luminous flux coupling element 10, and display positions A, B of display information of the display element 22, and image forming positions A', B' are varied to match the environmental condition under which the device is placed. In such a way, in a visual field position corresponding to, for instance, a car speed, both the display information and other image information can always be observed in a satisfactory state.
