摘要:
The transparent conductive film of the present invention is a transparent conductive film, comprising: a transparent film substrate; a patterned transparent conductive layer formed on one side of the transparent film substrate; and a colored layer provided on at least one of an opposite side of the transparent conductive layer from the transparent film substrate and an opposite side of the transparent film substrate from the transparent conductive layer, wherein the colored layer has an average absorptance of from 35% to 90% for light in the wavelength range of from 380 nm to 780 nm.
摘要:
A method of continuously subjecting an elongated substrate to vacuum film formation is disclosed. The method comprises the steps of: feeding a first substrate from a first roll chamber in a first direction from the first roll chamber toward a second roll chamber; degassing the first substrate; forming a film of a second material on the first substrate, in a second film formation chamber; and rolling up the first substrate in the second roll chamber, thereby producing the first substrate, and comprises similar steps to produce a second substrate. In advance of producing the first substrate with the second material film, the first cathode electrode of the first film formation chamber is removed from the first film formation chamber, and, in advance of producing the second substrate with the first material film, the second cathode electrode of the second film formation chamber is removed from the second film formation chamber.
摘要:
The present invention provides a transparent conductive film in which the difference in visibility between the pattern portion and the pattern opening portion is kept small even when a transparent conductive layer is patterned. The transparent conductive film has a first dielectric layer, a second dielectric layer, and a transparent conductive layer in this order on a transparent film substrate, a thickness d21 of the first dielectric layer is larger than a thickness d22 of the second dielectric layer, the thickness d21 of the first dielectric layer is 8 to 40 nm and the thickness d22 of the second dielectric layer is 5 to 25 nm, and a difference between the thickness d21 of the first dielectric layer and the thickness d22 of the second dielectric layer, d21-d22, is 3 to 30 nm.
