Abstract: Disclosed herein are an anti-reflection polarizing film and a display device having the same. The anti-reflection polarizing film includes: a polarization layer configured to linearly polarize external light; a phase-difference layer configured to circularly polarize the light transmitted through the polarization layer; a first support layer between the polarization layer and the phase-difference layer, configured to protect the polarization layer; and a second support layer facing the first support layer with the polarization layer therebetween, configured to protect the polarization layer, wherein a part of a particular layer among the layers facing the second support layer is extended towards an edge.

Abstract: A display device and a method for manufacturing the same are disclosed, in which a cathode electrode is not separated from an organic light emitting layer. The method for manufacturing a display device comprises the steps of forming pixels on a display area on a first substrate, forming an encapsulation film to cover the display area, attaching a protective film onto the encapsulation film, and removing the protective film. When attaching the protective film, the protective film includes a substrate layer and an adhesive layer formed at an edge area of at least one side of the substrate layer.

Abstract: Discussed herein is an organic light-emitting display (OLED) device that may include an organic light-emitting element layer disposed on a substrate; and an encapsulation layer covering the organic light-emitting element layer to block moisture and/or oxygen from permeating, wherein the encapsulation layer includes a barrier film having at least one transmittance adjusting layer that adjusts a ratio at which light emitted from the organic light-emitting element layer exits the OLED device, whereby the use of a polarizer is avoided.
