A display device is provided with a light source, an light-guide plate, a prism sheet, a transparent/scattering state switching element, and a transmissive liquid crystal display panel. In the transparent/scattering state switching element, two transparent substrates are provided parallel to and separated from each other, and an electrode is provided to the surface of each transparent substrate. A scattering seal member is also provided between external peripheral portions of the transparent substrates, and a PDLC layer is enclosed in a space sealed by the scattering seal member between the transparent substrates. The scattering seal member is endowed with scattering properties whereby incident light is transmitted in a scattered state, and the degree of scattering thereof is equal to the degree of scattering of the PDLC layer during the scattering state. |
