绝缘间隔层430a设置于第一感测层410a和第二走线层420a上。具体地，在第一感测层410a和第二走线层420a上涂布适当厚度的绝缘材料，在涂布的绝缘材料固化之后形成绝缘间隔层430a。
第二感测层440a设置于绝缘间隔层430a上。第二感测层440a包括多个第二感测条441a，每个第二感测条441a沿列方向延伸，并且这些第二感测条441a彼此平行且分离，换句话说，相邻的两个第二感测条441a在行方向上彼此平行且相互不接触。需要说明的是，本发明并不对第二感测条441a的数量作具体限定，它们可以根据实际需求而设置。此外，在本实施例中，第二感测条441a呈矩形状，但本发明并不限制于此，例如第二感测条441a也可以采用 第二感测串420的结构。另外，在本实施例中，第二感测条441a是由碳纳米管、纳米银线和纳米银颗粒中的一种制成的呈薄膜状的薄膜电极，但本发明并不限制于此。
第一走线层500设置于触控电极薄膜层400上且位于第二感测层440a的侧端。在本实施例中，第一走线层500用于与第二感测层440a连接，以传递电信号。
