Abstract: An embodiment of the present disclosure provides a dimming glass, including: a glass substrate; and at least two dye liquid crystal cells on the glass substrate. The dye liquid crystal cells are mutually stacked and bonded with each other via an adhesive layer. The dye liquid crystal cell includes a central region and a peripheral region surrounding a periphery of the central region. The dye liquid crystal cell includes a cell gap adjusting structure in at least the peripheral region, which is configured to adjust a cell gap of the dye liquid crystal cell to be consistent. An embodiment of the present disclosure further provides a transportation device, including the dimming glass described above and used as a window glass of the transportation device.
