| Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a touch panel in which interference fringes appearing in a transparent part as a display region, that is, between a transparent adhesive layer and a transparent protective layer on a transparent resin substrate, are suppressed and excellent visibility is achieved, and a method for manufacturing the touch panel.SOLUTION: A touch panel 10 includes a transparent adhesive layer 2, an electrode line 4, and an insulating transparent protective layer 6 successively layered on at least one surface of a transparent substrate 1. The surface of the transparent adhesive layer 2 in a non-electrode line region has an arithmetic average roughness Ra of 0.1 to 0.2 μm; and the insulating transparent protective layer 6 in the non-electrode line region has a haze value of less than 5%.SELECTED DRAWING: Figure 1
【課題】表示領域である透明部、すなわち透明樹脂基材上の透明接着層と透明保護層間との間で生じる干渉縞を抑制し、視認性に優れたタッチパネル及びその製造方法を提供することを目的とする。【解決手段】透明基材１の少なくとも一方の面に透明接着層２、電極線４、絶縁性を有する透明保護層６が順次積層されてなるタッチパネル１０であって、前記透明接着層２の非電極線領域の表面の算術平均粗さＲａが０．１〜０．２μｍで、前記絶縁性を有する透明保護層６の前記非電極線領域でのヘイズ値が５％未満であることを特徴とするタッチパネル１０である。【選択図】 図１ |
