Patent number: 9609745Abstract: A transparent conductive film includes a film base, a cured resin layer formed at one side of the film base, and an indium composite oxide layer laminated at a side of the cured resin layer opposite to the film base. The indium composite oxide layer has a thickness of 20 nm to 50 nm. The cured resin layer has a plurality of spherical particles and a binder resin layer which fixes the plurality of spherical particles to the film base. A difference w?d between a mode particle size w and a thickness d of the binder resin layer is greater than zero and less than or equal to 1.2 ?m, where w is a mode particle size of the spherical particles and d is a thickness of the binder resin layer.Type: GrantFiled: December 10, 2012Date of Patent: March 28, 2017Assignee: NITTO DENKO CORPORATIONInventors: Katsunori Takada, Kazuhiro Ikai, Hiroki Kuramoto, Hiroyuki Takao, Naoki Tsuno
