Optical member for enhancing luminance and organic light-emitting display device having the same

An organic light-emitting display device, comprising:

• an optical member for luminance enhancement and reducing reflection, the optical member comprising:
• 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, and
• wherein the optical member is on an upper surface or a lower surface of a substrate including a plurality of organic light-emitting diodes and TFT arrays.
