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.

Panel device

An EL emitting touch switch includes first electrodes, a single second electrode facing the first electrodes, and EL layers each sandwiched between a corresponding one of the first electrodes and the second electrode. A light emission driver applies a driving voltage between the first and second electrodes to cause the EL layers to emit light. A timing signal generator generates a timing signal to control the light emission driver such that the application of the driving voltage is stopped at predetermined intervals. Touch decision units are provided for each first electrode. Each touch decision unit includes a feedback circuit for supplying current to the corresponding first electrode such that the potentials of the first and second electrodes become equal to each other, and detects contact of a human body with the corresponding first electrode based on operation of the feedback circuit while the application of the driving voltage is stopped.
