項に記載のパネルスイツチ。[Claims for Utility Model Registration] (1) A display panel consisting of a liquid crystal display element having at least one display part, and one display panel arranged for each display part of the liquid crystal display element at the bottom of the display panel. Infrared light emitted from an infrared light emitting element that emits a predetermined infrared light and a pair of infrared light emitting elements arranged one for each infrared light emitting element at the bottom of the display panel. It includes an infrared light receiving element that receives the reflected light and converts it into an electrical signal when it is reflected by an object above the display panel, and a controlled device that is controlled by the electrical signal from each light receiving element, and the above-mentioned A reflective plate or a transparent plate disposed on the back surface of the liquid crystal display element constituting the display panel has a mesh-like transparent plate in the area where the infrared light should pass in the area facing each display part of the liquid crystal display element. A panel switch characterized by being equipped with a light section. (2) Utility model registration claim 1, characterized in that the light-transmitting part of the reflective plate or the transparent plate is formed by a large number of mesh-shaped holes.
Panel switch described in section. (3) The reflective plate or transmissive plate is constructed by printing a predetermined pattern in multiple colors on a transparent plate material, and the transparent part is kept transparent in a mesh shape without applying the above printing. The first claim for utility model registration is
Panel switch described in section.
