Title:
RETARDATION FILM, METHOD FOR PRODUCING TRANSPARENT CONDUCTIVE LAMINATE FOR TOUCH PANEL, AND THE TOUCH PANEL
Document Type and Number:
Japanese Patent JP2011043628
Kind Code:
A
Abstract:
To provide a retardation film for a touch panel.
The touch panel 100 is formed by arranging two substrates 110, 120 each having a transparent conductive film formed on the surface while leaving a predetermined gap so that the transparent conductive films 112, 122 are opposed to each other where at least one substrate 111 is a retardation film which is formed of an added (co)polymer of cyclic olefin having a copolymerization ratio of norbornene to an ethylene of 80:20 to 90:10, a melt volume rate (MVR) of 0.8 to 2.0 cm3/10 minutes, and a glass transition temperature of 170 to 200, and which shows the retardation of 100 to 150 nm.
