  • POLARIZING PLATE FOR OLED AND DISPLAY DEVICE COMPRISING THE SAME
    Publication number: 20210408497
    Abstract: A polarizing plate and a display device including the polarizing plate are disclosed. The polarizing plate is suitable for OLED and contains a polarizer, a moisture barrier layer, and a retardation layer, which are sequentially laminated. The moisture barrier layer is disposed on the opposite side of the viewing side of the polarizer and has a water vapor transmission rate of 450 g/m2ยท24 hr or less. The retardation layer comprises a ?/4 retardation layer, and a display device comprising the same. The polarizing plate can be made thinner, prevent reverse curling, suppress migration of iodine in a polarizer to prevent corrosion of a metal electrode of a lower panel, facilitate post-treatment such as polarizer bleaching, and prevent retardation changes even in a high-humidity environment.
