To provide a touch display module having sufficiently low reflectance, configured to reduce reflected light from an external environment, and having no effect on display quality.SOLUTION: A touch display module 100 includes a touch device 110 and a polarization element 150. The polarization element includes a polarizer 160 and a retardation film assembly 170. The retardation film assembly has a polarization ellipticity value (e value). An absolute value of the e value is larger than 0.8. A reflectance of the polarization element is less than 6%. Total reflectance of the touch device and the polarization element is less than 7%.SELECTED DRAWING: Figure 1 【課題】十分に低い反射率を有し、外部環境からの反射光を低減し、ディスプレイ品質に影響を与えない、タッチ表示モジュールを提供する。【解決手段】タッチ表示モジュール１００は、タッチ装置１１０と偏光素子１５０とを含む。偏光素子は、偏光子１６０とリタデーションフィルムアセンブリ１７０とを含む。リタデーションフィルムアセンブリは、偏光楕円率値（ｅ値）を有し、ｅ値の絶対値は、０．８より大きい。偏光素子の反射率は、６％未満であり、タッチ装置及び偏光素子の全反射率は７％未満である。【選択図】図１
