ABSTRACT:
A touch panel includes a light-transmittable upper substrate, a light-transmittable upper resistor layer on a lower surface of the upper substrate, a light-transmittable lower substrate, a light-transmittable lower resistor layer on an upper surface of the lower substrate, an adhesive layer on an upper surface of the upper substrate, and a light-transmittable plate on the adhesive layer. The upper substrate is made of material having oxygen and nitrogen removed therefrom. The lower resistor layer faces the upper resistor layer by a distance. The light-transmittable plate disables oxygen and nitrogen to pass through the plate substantively. Even being used in high temperatures, this touch panel does not produce an air bubble in the adhesive layer, hence allowing a user to clearly view a display device through the touch panel.
