Title:
TRANSPARENT FILM, MANUFACTURING METHOD THEREFOR, TRANSPARENT CONDUCTIVE FILM, TOUCH PANEL, ANTI-REFLECTIVE FILM, POLARIZING PLATE, AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2015/115534
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a transparent film with suppressed dimensional shrinkage even when subjected to high humidity over a long period of time, and providing a manufacturing method therefor, a transparent conductive film, a touch panel, an anti-reflective film, a polarizing plate, and a display device. According to the present invention, provided is a transparent film in which formulas (1) and (2) are satisfied, Rth representing birefringence in the thickness direction normalized to a thickness of 100 μm is 1-50 nm, and the in-plane distribution of Rth is 1-50%. Formula (1): 130≤T≤200, and formula (2): 0≤Y<0.4, where, in formulas (1) and (2), T is the glass transition temperature of the transparent film, Y is the equilibrium moisture content of the transparent film at 25°C, the glass transition temperature is in units of °C, and the equilibrium moisture content is in units of mass%.
