Abstract

In order to achieve responsiveness with excellent linearity, with a simple construction and low cost, a first resistor layer formed on at least a first substrate, of the first substrate and a second substrate that are arranged facing each other, is divided to form a plurality of first divided resistor layers (31a-31e), and each of the first divided resistor layers are arranged side by side in the longitudinal direction (Y) with gaps interposed therebetween. The lengths of first wiring layers, each of which is connected to a different layer among the first divided resistor layers (31a-31e), are all different from each other. The average width of a first wiring layer is formed to become wider as the length of the first wiring layer becomes longer.

Description

technical field [0001] The present invention relates to a resistive input device capable of multi-touch input, and more particularly to a wiring layer structure. Background technique [0002] The following patent documents disclose structures of resistive input devices capable of multi-touch input. In the resistive input device, the second substrate and the first substrate are arranged to face each other with a gap in the height direction. Each substrate is configured to have a base material and a resistive layer formed on the surface of the base material. In an input device capable of multi-touch input, a resistive layer formed on a surface of a substrate is divided into multiple layers, and both sides of each divided resistive layer are electrically connected to a wiring layer made of a conductive material. [0003] Figure 7 This is a plan view showing one of the substrates constituting one of the input devices as a comparative example to the present invention. Here, o...
