TOUCH PANEL DEVICE

To maintain or improve detection accuracy of a touch operation location on a touch panel.SOLUTION: In a touch panel device according to the present invention, a plurality of detection areas are arranged in a matrix, transmission wiring and reception wiring corresponding to each of the detection areas are formed. In one direction, a transmission wiring arrangement area in which the transmission wiring is arranged, the detection area, and a reception wiring arrangement area in which the reception wiring is arranged are formed so as to be juxtaposed. When an interval width from a certain detection area to a next detection area via the reception wiring arrangement area and the transmission wiring arrangement area in the one direction is BW, a width in the one direction of the detection area is AW, and a touch diameter is TC, a value calculated from "AW+2*BW-TC" is smaller than a target value of coordinate location accuracy.SELECTED DRAWING: Figure 11 【課題】タッチパネルにおけるタッチ操作位置の検出精度を維持又は向上させることを目的とする。【解決手段】本発明におけるタッチパネル装置は、複数の検出領域がマトリクス状に配置され、各前記検出領域に対応して送信配線と受信配線が形成され、一の方向に、前記送信配線が配置された送信配線配置領域と、前記検出領域と、前記受信配線が配置された受信配線配置領域とが並ぶように形成されており、或る前記検出領域から前記一の方向に前記受信配線配置領域と前記送信配線配置領域を介した次の前記検出領域までの間隔幅をＢＷ、前記検出領域の前記一の方向における幅をＡＷ、タッチ径をＴＣとしたときに、「ＡＷ＋２×ＢＷ−ＴＣ」から算出される値が座標位置精度の目標値よりも小さくなる。【選択図】図１１
