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.
