Problems solved by technology

However, when the above-mentioned two conductive sheets are laminated, the fine metal wires of the respective conductive sheets will come close to each other due to positional displacement generated in the assembly process, etc. Adjacent to each other in the x and y directions without a gap forms a bundle. As a result, the bundle becomes visible and the visibility of the touch panel may decrease.

Abstract

A conductive sheet pair that does not impair visibility when being stacked is provided. The conductive sheet pair includes a first conductive sheet including a first conductive pattern including a first pattern region in which a plurality of repetitions of a first geometric figure formed of conductive lines are arranged and a first blank region in which the repetitions of the first geometric figure are not arranged, and a second conductive sheet including a second conductive pattern including a second pattern region in which a plurality of repetitions of a second geometric figure formed of conductive lines are arranged and a second blank region in which the repetitions of the second geometric figure are not arranged. The sizes and the relative positions of the first blank region and the second blank region are adjusted so that the first pattern region and the second pattern region do not overlap each other when the first conductive sheet and the second conductive sheet are aligned and stacked together. The pattern regions located side by side with the blank region formed on the second conductive sheet in between are connected by a connection pattern.

Description

technical field [0001] The invention relates to a pair of conductive sheets and a touch panel, for example, a pair of conductive sheets suitable for a capacitive touch panel and a touch panel. Background technique [0002] In recent years, in the fields of information terminals such as smartphones and tablet PCs, touch panels are often used. At present, the application of touch panels to small devices such as information terminals has become the mainstream, but it is believed that in the near future, by applying to monitors of desktop PCs, etc., they can be enlarged. When ITO (Indium Tin Oxide) is used for the electrodes of the touch panel, as the size of the touch panel increases, the current transmission speed between the electrodes becomes slower and slower, and the response speed until the touch of the fingertip is detected becomes slower. class questions. In this regard, for example, Patent Document 1 (Japanese Patent Laid-Open No. 2012-238274 ) discloses a conductive...
