• Subjects: DEVICES OR ARRANGEMENTS, THE OPTICAL OPERATION OF WHICH ISMODIFIED BY CHANGING THE OPTICAL PROPERTIES OF THE MEDIUM OF THEDEVICES OR ARRANGEMENTS FOR THE CONTROL OF THE INTENSITY,COLOUR, PHASE, POLARISATION OR DIRECTION OF LIGHT, e.g.SWITCHING, GATING, MODULATING OR DEMODULATING; FREQUENCY-CHANGING; NON-LINEAR OPTICS; OPTICAL ANALOGUE/DIGITAL CONVERTERS; OPTICAL ELEMENTS, SYSTEMS, OR APPARATUS; OPTICAL LOGIC ELEMENTS; OPTICS; PHYSICS; TECHNIQUES OR PROCEDURES FOR THE OPERATION THEREOF

PROBLEM TO BE SOLVED: To provide a polarizing plate which includes a protective layer arranged in a liquid crystal cell side and having in-plane retardation Reof nearly zero and retardation Rthin a film thickness direction of nearly zero and is made thin and light and includes excellent durability, and particularly, is suitably used for an in-plane switching mode liquid crystal display, and to provide a method for manufacturing the polarizing plate, and the liquid crystal display using the polarizing plate. SOLUTION: The polarizing plate includes: a polarizing film 51 where a dichroism pigment is adsorbed and oriented to a polyvinyl alcohol resin; a first protective film 52 laminated on one surface of the polarizing film 51 and is composed of a cured product of a curable resin composition containing an active energy ray-curable compound; and a second protective layer 53 laminated on the other side surface of the polarizing film 51 across an adhesive layer 54 and composed of a thermoplastic resin film. The method of manufacturing the same and the liquid crystal display using the polarizing plate are also provided. COPYRIGHT: (C)2010,JPO&INPIT
