Circular polarizers consisting of a λ/4 retardation film and a polarizer are used in OLED displays to prevent glare (reflection). In the ideal case where the transmittance of the absorption axis of the polarizer is zero, the polarizer should be laminated at an angle of π/4. However, we have derived the lamination angle that minimizes the reflected transmittance when the transmittance of the absorption axis is not zero, assuming an actual polarizer.
