ELECTROCHROMIC DEVICE, OPTICAL FILTER, LENS UNIT, AND IMAGING APPARATUS |
| 摘要 |
The present invention provides an electrochromic device including a pair of electrodes and an electrochromic layer disposed between the pair of electrodes and containing different electrochromic materials having the same polarity, wherein in the case where two materials are selected from the different electrochromic materials having the same polarity in descending order of maximum absorbance in a color-display mode of the electrochromic layer and where the diffusion coefficients of the molecules of the two materials are compared with each other in the color-display mode, a smaller diffusion coefficient D2min, a larger diffusion coefficient D2max, and maximum absorbance H2 of the molecules of the electrochromic material having the diffusion coefficient D2max in the color-display mode satisfy Formula (5).;1≦D2max/D2min≦(1+0.146/H2)2 (5) |
