UPPER PLATE POLARIZING PLATE AND AN LCD DEVICE FOR IN PLANE SWITCHING MODE INCLUDING AND UPPER PLATE POLARIZING UPPER PLATE, CAPABLE OF ENABLING MASS PRODUCTION AS EASILY MANUFACTURING COMPLEX POLARIZING PLATE THROUGH A PRODUCTION TYPE OF A ROLL TO ROLL TYPE PRODUCTION

摘要

PURPOSE: An upper plate polarizing plate and a LCD device for in plane switching mode including and upper plate of polarizing upper plate are provided to maintain absorbing axes between polarizers of an upper plate polarizing plate and a lower plate polarizing plate on a slope by an orthogonal state, thereby preventing light leakage.;CONSTITUTION: A positive axial A plate(24), a positive biaxial A plate(25), a polarizer(21) and a protection layer(23) are successively laminated from a liquid crystal cell side in orders, in an upper plate polarizing plate for IPS(In Plane Switching) mode(20). A front phase difference value of a positive uniaxial A plate is 80-130nm. A slow phase axis of the positive axial A plate is parallel to an absorption axis(22) of an adjacent polarizer. The front phase difference value of the positive biaxial A plate is 40-90nm.;COPYRIGHT KIPO 2010
