    Abstract: A display switching device according to one or more embodiments may display images by switching light illumination from multiple light source positions. The device may include a lens array including multiple lenses that allow passage of light from the light source positions, a display layer including pixel regions that allow passage of light collected on the lenses included in the lens array, and a diffusion layer located opposite to the light source positions with the lens array in between to diffuse passing light. The diffusion layer optically adheres to a layer adjacent to a surface of the diffusion layer nearer the light source positions, or the diffusion layer and the layer adjacent the surface of the diffusion layer nearer the light source positions include the same material.
