ORIGINAL COATING ONE, size 26*19mm, coating is gold/pink color. (some projector may use red film one or silver coating one, both same)

This is a blue in poloarizer without housing, it is outside the lcd unit. 
Don't touch the surface with your finger or clean it by cloth, cause it is easy to broken the coating.

if your projector show yellow color on image, you can check if this one broken. and if the blue out polarizer which inside the LCD unit
broken can cause yellow color on image also.

other EPSON polarizer need please feel free to ask.
