Patent ID: 7820294

Claim:
A touch panel comprising: an upper substrate being light-transmittable and having an upper surface and a lower surface; an upper resistor layer being light-transmittable and being provided on the lower surface of the upper substrate; a lower substrate being light-transmittable and having an upper surface and a lower surface; a lower resistor layer being light-transmittable and being provided on the upper surface of the lower substrate, the lower resistor layer facing the upper resistor layer by a distance; an adhesive layer coupled to the upper surface of the upper substrate; and a plate being light-transmittable and being provided on the adhesive layer, the plate disabling oxygen and nitrogen to pass through the plate substantively, wherein the upper substrate is made of material having oxygen and nitrogen removed therefrom and replaced with water the plate allows molecules of water to pass through the plate; and the adhesive layer is provided on the upper surface of the upper substrate.
