Document Type and Number:
WIPO Patent Application WO/2018/181414
Kind Code:
A1
Abstract:
The present invention provides a polarizing film with added adhesive layer for realizing an in-cell liquid crystal panel which has excellent heat resistance and in which the antistatic function is satisfactory and it is possible to suppress static electricity–related anomalies while satisfying touch sensor sensitivity. This polarizing film with added adhesive layer is provided with an adhesive layer and a polarizing film, and is characterized in that: the polarizing film includes at least a polarizer and a transparent protective film; at least the polarizing film and the adhesive layer are provided in this order from the viewing side; the adhesive layer includes an antistatic agent; the adhesive layer–side surface resistance is 1.0×108 to 1.0×1011 Ω/□, said surface resistance being determined when removing a separator directly after preparing a polarizing film with added adhesive layer wherein the aforementioned adhesive layer is provided to the aforementioned polarizing film with the separator being provided to the adhesive layer; and the moisture permeability of the transparent protective film at 40°C×92% RH is 900 g/(m2·24h) or less.
