Claim 13:
14. 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 first polarizer further comprises a bonding protective layer located on a side of the first metal wire-grid polarizer facing the third substrate, and a side of the bonding protective layer away from the first metal wire-grid polarizer is bonded to the third substrate, a side of the second substrate facing the third substrate is provided with a second polarizer; the second polarizer comprises a second metal wire-grid polarizer, a third transparent protective layer and a fourth transparent protective layer that are sequentially located on the second substrate; and the second metal wire-grid polarizer is between the third transparent protective layer and the second substrate, a material of the third transparent protective layer is silicon oxide, a thickness of the third transparent protective layer is in a range from 1000 angstroms to 2000 angstroms; a material of the fourth transparent protective layer is amorphous silicon, and a thickness of the fourth transparent protective layer is in a range from 60 angstroms to 100 angstroms.
