1. A high transmittance touch panel comprising:
- a transparent substrate; and
a transparent multi-layered structure disposed on said substrate and including transparent inner and outer anti-reflection layers and a transparent touch control layer that is sandwiched between said inner and outer anti-reflection layers and that is made from an electrically conductive material, said inner anti-reflection layer having a first anti-reflection film, at least one of said outer anti-reflection layer and said first anti-reflection film having an optical thickness sufficient for generating destructive interference among reflections from said substrate, said outer anti-reflection layer, said first anti-reflection film, and said touch control layer.

Abstract
A touch panel includes: a transparent substrate; and a transparent multi-layered structure disposed on the substrate and including transparent inner and outer anti-reflection layers and a transparent touch control layer that is sandwiched between the inner and outer anti-reflection layers and that is made from an electrically conductive material. The inner anti-reflection layer has an anti-reflection film. At least one of the outer anti-reflection layer and the anti-reflection film has an optical thickness sufficient for generating destructive interference among reflections from the substrate, the outer anti-reflection layer, the anti-reflection film, and the touch control layer.

15. A capacitive-type touch panel comprising:
-
a transparent substrate; and a transparent multi-layered structure disposed on said substrate and including transparent inner and outer anti-reflection layers, said inner anti-reflection layer having a first anti-reflection film, and a transparent touch control layer that is sandwiched between said inner and outer anti-reflection layers and that is made from an electrically conductive material, said touch control layer including a plurality of spaced apart electrodes sandwiched between said outer anti-reflection layer and said inner anti-reflection layer, said multi-layered structure defining a plurality of first regions, each of which includes a portion of said inner anti-reflection layer and a portion of said outer anti-reflection layer that covers said portion of said inner anti-reflection layer, said multi-layered structure further defining a plurality of second regions, each of which includes another portion of said inner anti-reflection layer, a respective one of said electrodes that covers said another portion of said inner anti-reflection layer, and another portion of said outer anti-reflection layer that covers said one of said first and second electrodes; wherein at least one of said outer anti-reflection layer and said first anti-reflection film has an optical thickness sufficient for generating destructive interference among reflections from said substrate, said outer anti-reflection layer, said first anti-reflection film, and said touch control layer so as to cause reflections from said touch control layer to interfere destructively with reflections from at least one of said substrate, said outer anti-reflection layer, and said first anti-reflection film. - View Dependent Claims (16, 17, 18, 19)
