Publication number: 20090160819Abstract: The present invention is an inner touch panel in which a 1st and a 2nd planer member, each having an electrode disposed on one surface thereof, oppose each other with a fixed space therebetween. The electrodes face each other across the space, and a polarizing plate is stacked on the other surface of the 1st planer member. At least one of the 1st and the 2nd planer members is a film made of a siloxane crosslinking acrylic silicone resin. Here, in the case of having a thickness in the range of 0.1 mm and 0.4 mm, the film maintains, after heat treatment at 120° C. for 1000 hours, 96% or more of the visible light transmittance at a wavelength of 400 nm before the heat treatment.Type: ApplicationFiled: September 7, 2005Publication date: June 25, 2009Inventors: Kuniaki Sasaki, Kunitomo Tsureyama, Shuji Furukawa, Hirotoshi Sato, Tsutomu Yamada, Keiji Tsukamoto, Masanori Yamamoto, Takumi Sakamoto, Hideaki Mizumoto
