A display assembly, includes: a first substrate and a second substrate that are disposed opposite, a first liquid crystal layer located between the first substrate and the second substrate, a third substrate disposed at a side of the first substrate away from the second substrate, a second liquid crystal layer located between the first substrate and the third substrate, a first pixel circuit layer disposed between the first substrate and the first liquid crystal layer, a second pixel circuit layer disposed between the third substrate and the second liquid crystal layer, a polarizing device disposed on a side of the second pixel circuit layer away from the second liquid crystal layer, and a first metal wire grid polarizing layer disposed between the first substrate and the first pixel circuit layer. The first metal wire grid polarizing layer is electrically insulated from the first pixel circuit layer.
