Optical member and OLED display device
The invention discloses an optical member and an OLED display including an optical member. The optical member includes: a metal electrode, a λ/4 phase-difference plate and a linear polarization plate sequentially arranged in this order. A λ/2 phase-difference plate and a brightness enhancement film are arranged between the λ/4 phase-difference plate and the linear polarization plate; there is an angle between an absorption axis of the linear polarization plate and a polarization axis of the brightness enhancement film; and there is an angle between the polarization axis of the brightness enhancement film and a slow axis of the λ/2 phase-difference plate. This arrangement can address the problem in the related art that faces the difficulty to improve the transmittivity of light in an optical member in an OLED display.
