Abstract:
Thickness and weight are lowered while reducing warping and guaranteeing visibility of the screen. Included are a transparent panel substrate including a transparent resin base and a transparent resin layer formed on one surface of the transparent resin base; a decorative printing layer formed at an outer edge of a back surface of the transparent panel substrate; a warping prevention layer, formed to be flat and to cover the back surface of the transparent panel substrate inside the decorative printing layer and a back surface of the decorative printing layer; a transparent electrode layer formed on a back surface of the warping prevention layer; a jumper wiring layer formed on the transparent electrode layer and provided with an insulating layer; and a transparent protective layer formed on and entirely covering the jumper wiring layer except for a thermocompression bonding region of a substrate for external connection.
Abstract:
Provided is a curved capacitive touch panel including a curved capacitive touch panel substrate including: a transparent panel substrate; a decorative print layer disposed on a peripheral section of a rear surface of the transparent panel substrate; a step prevention layer flatly covering across a rear surface of the decorative print layer and inward of the decorative print layer on the rear surface of the transparent panel substrate; a sensor section including a transparent electrode layer that is disposed on a rear surface of the step prevention layer; and a transparent protective film covering the entire surface of the sensor section with the exception of a thermal compression bonding region substrate. The touch panel also includes an external connection substrate bonded by thermal compression to the thermal compression bonding region.
