  • Patent number: 11518919
    Abstract: An optical laminate includes two substrates each of which has a tensile modulus in a range from 2,000 MPa to 7,500 MPa, and an adhesive layer interposed between the substrates. A storage modulus at 25° C. of the adhesive layer is 100 kPa or less, and a storage modulus at ?20° C. of the adhesive layer is equal to or less than three times the storage modulus at 25° C. of the adhesive layer. The optical laminate and an image display device including the optical laminate may have an improved flexible property at various temperature ranges and may be capable of minimizing cracks when being bent.

  • Patent number: 10644258
    Abstract: An organic light emitting diode (OLED) panel includes an OLED module layer, and a first adhesive layer formed on a surface of the OLED module layer. A neutral plane is formed at an interface between the first adhesive layer and the OLED module layer. A bending deformation and a stress of the OLED module layer may be avoided, and damages of the OLED module layer may be reduced.

  • Patent number: 10495799
    Abstract: The present invention provides an ultra thin polarizing plate comprising a polarizer, a protective film formed on one surface of the polarizer, and an adhesive layer formed on the other surface of the polarizer, wherein the protective film has a resisting force of 2.1 to 18.7 N, and a liquid crystal display device having the ultra thin polarizing plate. The ultra thin polarizing plate according to the present invention can inhibit curl occurrence to prevent bonding defects by the curl in the process that the polarizing plate is bonded to a liquid crystal cell, and can make the thickness of the protective film thin, and therefore it can be effectively used in a flexible display.
