とする、パネルスイツチ。 A display panel consisting of a liquid crystal display element having at least one display part, and an infrared light emitting element disposed at the bottom of the display panel for each display part of the liquid crystal display element and emitting predetermined infrared light. When the infrared light emitted from the pair of infrared light emitting elements arranged one for each infrared light emitting element at the bottom of the display panel is reflected by the upper object of the display panel, It includes an infrared light-receiving element that receives this reflected light and converts it into an electrical signal, and a controlled device that is controlled by the electrical signal from each light-receiving element. 1. A panel switch, characterized in that the disposed reflective plate or transmissive plate is provided with a hole in a region through which the infrared light should pass in a region facing each display section of the liquid crystal display element.
