Claim 0:
1. A manufacturing method of a display device, comprising:
stacking a first substrate, a second substrate and a third substrate sequentially to form a liquid crystal display panel and a dimming panel; the liquid crystal display panel comprising the first substrate, the second substrate, and a display liquid crystal layer between the first substrate and the second substrate; the dimming panel comprising the second substrate, the third substrate, and a dimming liquid crystal layer between the second substrate and the third substrate; and
forming a first polarizer 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 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.
