Document Type and Number:
WIPO Patent Application WO/2015/076087
Kind Code:
A1
Abstract:
The present invention provides a capacitive touch panel which is not prone to operation errors in a wide range of temperature environments from low temperatures to high temperatures. This capacitive touch panel comprises, in the following order, a display device, a lower adhesive layer, a capacitive touch panel sensor, an upper adhesive later, and a protective substrate. The maxima of tanδ of the upper adhesive layer and the maxima of tanδ of the lower adhesive layer as derived from temperature-dependency evaluation tests are 0.08 or less. The tanδ of the lower adhesive layer at every 20°C in a range of -40-80°C is less than or equal to the tanδ of the upper adhesive layer.
