Abstract

A panel device includes a panel section, a first conductive layer that is provided in a side of one surface of the panel section, an insulating layer that is stacked on the first conductive layer and a second conductive layer that is stacked on the insulating layer. The first conductive layer and the second conductive layer are formed by coating an electrically conductive solvent-type substance. The insulating layer is formed by coating an insulating curing-acceleration-type substance.

Claims

1. A panel device comprising:

a panel section;

a touch sensing electrode provided directly on a surface in an area of the panel section;

a shield electrode provided in a side of the surface of the panel section except for the area without making electrical contact with the touch sensing electrode, and formed by coating an electrically conductive substance containing solvent;

a design layer provided between the surface of the panel section and the shield electrode;

an insulating layer that is stacked on the shield electrode except for the area and is formed by coating an insulating substance containing curing agent that accelerates curing; and

a connection pattern, formed by coating an electrically conductive substance containing solvent, and stacked on the insulating layer except for the area, the connection pattern having a portion extending towards the touch sensing electrode and making electrical contact with the touch sensing electrode without making electrical contact with the shield electrode,

wherein the shield electrode, the design layer, and the insulating layer define an aperture surrounding the area, and the touch sensing electrode is exposed through the aperture.
