DISPLAY DEVICE

摘要

In this mirror-switching display device which includes electrochromic elements, in a transparent mode, the electrochromic elements have a light transmittance of 70% or more and a light reflectance of 20% or less at the central wavelength in the visible light region, and in a mirror mode, have a light reflectance of 65% or more at the central wavelength in the visible light region when switching to the mirror mode. Thereby, the mirror-switching display device not only has excellent light shielding, thermal insulation, masking, and other properties, but is also capable of switching between transmission and reflection modes.
