The screenprotector you mean is likely a thick sheet of plastic, which protects the screen from "parts" you accidentaly drop at the screen, like the buildplate. If it's just to protect the LCD-screen from leaking resin, like a puncture or tear in FEPfilm, I advise a thin transparant sheet to cover the LCD-screen. You can tape this to the red plate. Such thin sheet can be bought at a copyshop, bookstore or officesupply-store and is cheaper than the thick screenprotector.
I just use ones for laptops and cut to size. Made a template on my Ender3 for cutting my VoxProx6 ones.
If you have one with black tape theres already a screen protector on it. Was there not a warning sticker not to peel it off? Mine had one
It says that’s the polarizer though, not a screen protector

YES! Screen protectors are worth it. Saves the time of replacing a screen if something goes askew.
