  • COMPOSITE POLARIZING PLATE
    Publication number: 20160291224
    Abstract: A composite polarizing plate includes a polarizing plate having a polarization coating layer formed on one surface thereof, a retardation coating layer, and a photo-curable adhesive layer installed between the polarizing plate and the retardation coating layer, such that a display device having a thinner thickness and lighter weight may be implemented, and cracks may be reduced due to excellent flexibility, thereby the composite polarizing plate may be applied to a flexible display device.
