Input device and method of manufacturing the same

摘要

A touch panel includes a transparent panel, a decorative layer which is formed in a decorative region on a first surface of the transparent panel, a transparent electrode which is formed from a transparent input region of the first surface to a surface of the decorative layer, and a wiring layer which is formed to extend to the surface of the decorative layer and electrically connected to the transparent electrode.

主权项

1. An input device comprising:
a transparent panel having an operating surface and a rear surface opposite to the operating surface; a non-light-transmissive decorative layer directly formed on a decorative region of the rear surface of the transparent panel, the decorative region surrounding a transparent input region of the rear surface, the decorative layer including:
a flat portion having a same thickness; anda tapered portion extending from the flat potion toward the transparent input region with a decreasing thickness such that an edge of the tapered portion of the decorative layer defining a boundary between the transparent input region and the decorative region, the tapered portion forming an inclined surface having an upward slope in a direction away from the transparent input region; a transparent electrode directly formed on the transparent input region of the rear surface of the transparent panel, the transparent electrode extending along the inclined surface onto the flat portion of the decorative layer so as to overlap the decorative layer; and a wiring layer electrically connected to the transparent electrode by overlapping the transparent electrode, the wiring layer only formed on the transparent electrode where the decorative layer is formed between the transparent panel and the transparent electrode in the decorative region, the wiring layer extending within the decorative region where the decorative layer is formed.
