Title:
ADHESIVE FILM HAVING A PHASE DIFFERENCE, METHOD FOR MANUFACTURING SAME, AND OPTICAL MEMBER INCLUDING SAME
Document Type and Number:
WIPO Patent Application WO/2013/035977
Kind Code:
A1
Abstract:
According to the present invention, an adhesive film having a phase difference is characterized by a phase difference value of 25°C/55% RH at a thickness of 20 µm being approximately 20 nm to approximately 150 nm, and 1 rad/s modulus by a frequency seep test at 30°C being approximately 105 dyne/cm2 to approximately 109 dyne/cm2. The adhesive film having a phase difference exhibits minimal entangling and retains an elongated structure under high temperatures and humidity so as to provide an optical member that has decreased light leakage, retains superior durability, reworkability, and adhesion, and has an excellent balance of physical properties.
