• 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; LAYERED PRODUCTS; LAYERED PRODUCTS, i.e. PRODUCTS BUILT-UP OF STRATA OF FLAT ORNON-FLAT, e.g. CELLULAR OR HONEYCOMB, FORM; NON-LINEAR OPTICS; OPTICAL ANALOGUE/DIGITAL CONVERTERS; OPTICAL ELEMENTS, SYSTEMS, OR APPARATUS; OPTICAL LOGIC ELEMENTS; OPTICS; PERFORMING OPERATIONS; PHYSICS; TECHNIQUES OR PROCEDURES FOR THE OPERATION THEREOF; TRANSPORTING

PROBLEM TO BE SOLVED: To provide a polarizing plate with a transparent electroconductive layer, in which the transparent electroconductive layer produces no crack over a long period of time, which keeps low resistance and has high strength and excellent mechanical durability even in use requiring severe heat resistance and moisture resistance such as an on-vehicle touch panel, and also to provide the touch panel having the polarizing plate. SOLUTION: Annular olefinic polymer layers are respectively laminated on both surfaces of a polarizing film, and the amorphous transparent electroconductive layer is laminated on a surface of at last one layer of the annular olefinic polymer layers opposite the polarizing film directly, or via other layer to form the polarizing plate. The touch panel having the polarizing plate is also provided. COPYRIGHT: (C)2009,JPO&INPIT
