Abstract
A display switching device (10) is provided, which switches a display image (P) by switching irradiation of lights from positions of a plurality of light sources (7). The display switching device includes: a lens array (6) in which a plurality of lenses are arranged; and a display part (45) including a plurality of pixel regions (45a) arranged to include a region through which a light, which is formed by condensing each of the lights emitted from the positions of the plurality of light sources (7) with each of the lenses of the lens array (6), passes. A transmittance in each of the pixel regions (45a) is set corresponding to a predetermined stationary pattern. A total area of the pixel regions (45a) in the display part (45) is 60% or less of a total area of a sum of the pixel regions (45a) and the pixel surrounding regions (45b).
