Document Type and Number:
WIPO Patent Application WO/2014/112323
Kind Code:
A1
Abstract:
[Problem] To provide: a polarizing plate with touch functionality for polarizing sunglasses and having increased thinness, a narrower rim, and superior production characteristics; a method for producing the polarizing plate; and a liquid crystal display device. [Solution] This polarizing plate with touch functionality for polarizing sunglasses is provided with: a polarizing plate used disposed at the front surface of the liquid crystal cells of a liquid crystal display device; and a capacitive film sensor member pasted to the surface of the polarizing plate at the reverse side from the surface facing the liquid crystal cells. The film sensor member is provided with: a transparent base film containing a λ/4 retardation film obtained by stretching in an oblique direction; a transparent conductive film formed in a manner so as to have an electrode pattern and a wire guide circuit pattern respectively at the two surfaces of the base film; and light-shielding conductive films each laminated onto the wire guide circuit pattern of the transparent conductive film.
