second direction in alternative embodiments the first touch electrodes 31 and the second touch electrodes 32 are disposed on the same side i e the same upper surface or the same lower surface of the first protective layer 21 the insulating layer 60 may be made of polymer i e polyimide or inorganic materials i e si sub 3n sub 4 or sio sub 2 etc it should be understood that other components will not be described in further details since their manufacturing method or materials have already been described in the first embodiment the manufacturing method of the touch display 400 is similar to that of fig2 the difference is that in step s 102 the first touch electrodes 31 are formed on the second protective layer 23 in step s 104 the second touch electrodes 32 are formed on the insulating layer 60 then the first protecting layer 21 the polarizer substrate 22 and the second protecting layer 23 with the nano silver touch electrodes 30 and are attached together in step s 106 thus forming the touch polarizer 20 it should be understood that in alternative embodiments the nano silver touch electrodes 30 may be formed on the same side i e the same upper surface or the same lower surface of the first protective layer 21 other steps are similar to the.
