Title:
METHOD FOR PRODUCING CAPACITIVE TOUCH PANEL SENSOR SUBSTRATE, CAPACITIVE TOUCH PANEL SENSOR SUBSTRATE, AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2013/038624
Kind Code:
A1
Abstract:
Provided is a production method whereby a touch panel sensor substrate of excellent display quality can be produced less expensively than with past production methods, and without diminished viewability despite the use of metal materials in connecting parts. The method is a method for producing a capacitive touch panel sensor substrate of a transparent substrate (10) onto which are formed a first transparent electrode (1), a second transparent electrode (2), a first connecting part (3), a second connecting part (4), an insulating layer (5), and takeoff wiring (20); characterized by including a step for forming the first connecting part (3), a step for forming the insulating layer (5), and a step for forming the second connecting part (4), the step for forming the insulating layer (5) being performed subsequent to either the step for forming the first connecting part (3) or the step for forming the second connecting part (4), the remaining step among the step for forming the first connecting part (3) and the step for forming the second connecting part (4) being performed subsequent to the step for forming the insulating layer (5), and the reflectivity of the second connecting part (4) and the takeoff wiring (20) being in a range of 0-30% inclusive.
