Abstract
A stack comprising a "polarizing element material film" and a "resin layer directly disposed on the aforementioned polarizing element material film," wherein the in-plane phase difference Re1 of the aforementioned polarizing element material film is greater than 50 nm, and the thickness T1 of the aforementioned polarizing element material film is 45 μm or less. Preferably, the aforementioned polarizing element material film is obtained by stretching it by a specific stretching factor X. A polarizing plate obtained using the aforementioned stack, a method for manufacturing the stack, a method for manufacturing the polarizing plate, and a method for manufacturing a display device are also provided.
