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.
Claims10
An organic light-emitting display device comprising:
- a substrate partitioned into a plurality of RGB sub-pixels and white sub-pixels;
- an overcoating layer provided on the substrate, the overcoating layer comprising a lens array provided at an emission region of each of the sub-pixels;
- an organic light-emitting diode provided on the overcoating layer;
- and
- an optical member provided under the substrate, the optical member comprising a phase difference layer, an optical device, and a linear polarizer,
- wherein the optical device comprises a reactive mesogen and a dye.
