The invention discloses a thin film sensor and a touch display. The thin film sensor comprises a base material, a metal nanowire layer and an optical adhesive layer, the metal nanowire layer is formed on the base material and comprises a plurality of electrode wires which are arranged at intervals. The optical adhesive layer is formed on the metal nanowire layer and is matched with the metal nanowire layer, so that under a weather-proof test of high temperature and high humidity (65 DEG C/90% RH/DC 5V/240 hours), the wire resistance change rate of the electrode wires is less than 10%, and the insulation resistance between two adjacent electrode wires is greater than 300 megohms. Therefore, the reliability of the thin film sensor can be improved. 一种薄膜感测器及触控显示器，所述薄膜感测器包含基材、金属纳米线层及光学胶层。所述金属纳米线层形成于所述基材上，并且包含相互间隔排列的多个电极线。所述光学胶层形成于所述金属纳米线层上，并且匹配所述金属纳米线层，以在高温高湿(65℃/90％RH/DC 5V/240小时)的耐候试验下，所述电极线的线阻变化率小于10％，并且相邻的两个所述电极线之间的绝缘阻抗大于300MΩ。借此能够提高所述薄膜感测器的可靠性。
