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.

First claim

What is claimed is:

1. A display device comprising:
a flexible display panel having a display area and a bezel area surrounding the display area;
a circularly-polarizing film on the display area of the flexible display panel, the circularly-polarizing film comprising a plurality of layers;
a circuit unit connected to the flexible display panel on the bezel area of the flexible display panel; and
an adhesive member present between the circularly-polarizing film and the circuit unit,
wherein the plurality of layers of the circularly-polarizing film comprises at least a polarization layer, a phase-difference layer, and a first support layer disposed between the polarization layer and the phase-difference layer,
wherein at least the phase-difference layer extends beyond remaining layers of the plurality of layers of the circularly-polarizing film towards an edge of the bezel area such that an upper surface and a side surface of the phase-difference layer are exposed and a part of the phase-difference layer is disposed in an area corresponding to the bezel area,
wherein the circuit unit and the phase-difference layer are positioned on a same surface of the flexible display panel,
wherein at least the polarization layer of the remaining layers of the circularly-polarizing film is positioned only on the display area of the flexible display panel and does not extend towards the edge of the bezel area, and
wherein the adhesive member covers at least the exposed upper and side surfaces of the part of the phase-difference layer disposed in the bezel area and a part of the circuit unit.

2. The display device of claim 1 , wherein the plurality of layers further comprises a second auxiliary support layer facing the first support layer with the polarization layer therebetween to protect the polarization layer, and
wherein the phase-difference layer is disposed below the second auxiliary support layer.

3. The display device of claim 1 , wherein some layers among the plurality of layers of the circularly-polarizing film extends towards another edge that is opposed to the bezel edge.
