Custom g-shock MIP LCD fix needed PLEASE HELP!

Hello,
I am almost positive that I am in the wrong area and I was hoping to figure this out on my own but I need help or maybe just a point in the right direction of where I could get the info/answer to help me rectify my idiot move.

situation:
-bought a GW-BX5600 g-shock negative display with the hope I could modify it to positive and back as I desired
-I have modded digital LCD STN watches and figured this display tech would be similar, and was wrong.
-removed top polarizer and noticed there was another “layer between top pol. film and top glass substrate layer.
-I noticed after cuting a corner of the “other layer” that the glass “sandwich” substrate stack looked purple but no longer the deep black like normal.
-this would seem to mean that the 'second mysterious layer” is some sort of optical glass retarder/switcher layer that is needed for a more desireable display resolution.
-My idiot-!!$ removed it.

since then I have tested many type of polarizer films iphone/gameboy/linear/circular to even just get it back to original bit at best the display is still just a bit off as far as color/tint/depth etc.

WHAT IS THIS CLEAR “SECOND LAYER” BETWEEN THE TOP POLARIZER AND THE TOP/FIRST GLASS LAYER OF THE DISPLAY?! oca? a second polarizer? unicorn dust in sheet film form?

please help,.. I know where I am writing this but ANY HELP/DIRECTION WOULD MAKE MY DAY! THANKS.

PRESENT STATE OF THE WATCH the display is different tints at different angles but not white on black like original

Below is the corner cut out that I spoke of,.. also before I removed the “second layer”

Corner turns purple when polarizer is rotated.

Hope you guys can help. Thanks.

original,.. should have left it alone,…

I purchased some OCA mobile phone adhesive film layer material that typically goes between the top glass that your fingers make contact with and the polarizer underneath it. Hope it works but I am just grasping at straws at this point.
