Abstract
Disclosed is an organic light-emitting display device having a micro lens array (MLA) structure applied to a display panel in order to improve light extraction efficiency. In the organic light-emitting display device, an optical device, including a reactive mesogen (RM) and a dye, is provided between a polarizer and a quarter wave plate (QWP) to block light spreading to a viewing angle, thereby reducing a diffuse reflection component due to the application of the MLA structure.
