Abstract:
A display device includes a light guiding panel 2 having an incoming surface 2a formed on one of side surfaces, a plurality of light sources (3-1 to 3-4) respectively corresponding to a plurality of patterns that can be displayed, and a controller 6 for controlling on and off of the plurality of light sources. The light guiding panel 2 has a first reflective surface (2d, 2e) formed on the other side surface of the light guiding panel 2, the first reflective surface reflecting light emitted from a first light source and entering the light guiding panel 2 through the incoming surface 2a, and changing the propagation direction of the light, and a plurality of prisms 11 which is formed on one surface 2b of the light guiding panel, is oriented toward light emitted from a light source corresponding to the pattern, entering the light guiding panel 2 through the incoming surface 2a, and directed to the pattern, and reflects the light so that the light is emitted through the other surface 2c of the light guiding panel.
