Abstract
A touch display module includes a touch device and a polarizing element. The polarizing element includes a polarizer and a retardation film assembly. The retardation film assembly has a polarization ellipticity value (e-value), and the absolute value of the e-value is greater than 0.8. A reflection rate of the polarizing element is less than 6%, and a total reflection rate of the touch device and the polarizing element is less than 7%.
