1. A touch display module, comprising:
a touch device; and
a polarizing element disposed on the touch device, the polarizing element comprising:
a linear polarizer; and
a retardation film assembly, wherein when an ambient light passes through the linear polarizer to generate a linearly polarized light, the linearly polarized light is converted into a circularly polarized light through the retardation film assembly, wherein a ratio of the linearly polarized light that is converted into the circularly polarized light is defined as a polarization ellipticity value of the retardation film assembly,
wherein an absolute value of the polarization ellipticity value is greater than 0.8 in a wavelength range of 450 nm to 650 nm, and
wherein a reflection rate of the ambient light passing through the polarizing element is less than 6% in the wavelength range of 450 nm to 650 nm.
