Claim 9:
10. A display device, comprising:
a first substrate;
a second substrate, configured to be cell-assembled with the first substrate to form a liquid crystal display panel;
a third substrate, configured to be cell-assembled with the second substrate to form a dimming panel; and
a first polarizer, located on a side of the third substrate away from the second substrate,
wherein the first polarizer comprises a first metal wire-grid polarizer and a transparent protective layer that are sequentially stacked, and the transparent protective layer is located on a side of the first metal wire-grid polarizer away from the third substrate;
the transparent protective layer comprises a first transparent protective layer in contact with the first metal wire-grid polarizer, and a second transparent protective layer located on a side of the first transparent protective layer away from the first metal wire-grid polarizer, a material of the second transparent protective layer is colorless polymide; the second transparent protective layer has a transparency greater than 90%, a yellowness index less than 5, and a thickness less than 5 microns, and the second transparent protective layer is configured as a back film of the dimming panel.
