Abstract: Provided are a very highly transmissive polarizing plate which allows for improved luminance efficiency without reducing the degree of polarization by enhancing the color of the polarizing plate, and an organic light-emitting display device having the same. With this very highly transmissive polarizing plate, the brightness, lifetime, and efficiency of the organic light-emitting display device can be improved, and at the same time power consumption can be reduced.

Abstract: Provided are an optical member for enhancing luminance and an organic light-emitting display device having the same. An optical member includes: a linear polarizer, a blue cholesteric liquid crystal (CLC) layer configured to transmit light, the light having only one of: a left-handed circularly polarized light component and a right-handed circularly polarized light component, and a quarter wave plate configured to convert the transmitted light, having the left-handed circularly polarized light component or right-handed circularly polarized light component, into linear polarized light, wherein the blue cholesteric liquid crystal (CLC) layer and the quarter wave plate are located on a same side of the linear polarizer.
