Abstract:
Provided is a display device capable of improving the design properties of a vehicle instrument panel. The display device comprises a light source 10 that emits light and a light-guide plate 11 that guides light incident from the light source 10. The light-guide plate 11 mounts a display device on an instrument panel, said display device having an emission surface 13 that emits light incident thereto and a plurality of light convergence units that change the route of incident light towards the emission surface 13 side, emit the incident light towards either a direction of an external convergence point or convergence line of a member itself or a direction in which light is dispersed from the external convergence point of convergence line of the member, and form an image on the outside of the member. The display device also provides three-dimensional display of a still image of, e.g, the digits 20a, scale lines 20b, and frame lines 20c, etc., of a speedometer 20.
