1. A flexible touch display module, comprising:
a flexible display panel;
a flexible cover plate disposed on a display side of the flexible display panel;
a linear polarization layer disposed between the flexible display panel and the flexible cover plate, and an absorption axis of the linear polarization layer is at an angle of about 90°;
a first retardation plate disposed between the linear polarization layer and the flexible cover plate, the first retardation plate comprising a first retardation film, the first retardation film being a liquid crystal layer with a quarter-wavelength retardation and having a major axis and a minor axis in a plane parallel to the flexible display panel, wherein an included angle between a direction in which the minor axis of the first retardation film extends and the absorption axis of the linear polarization layer is about 45°; and
a second retardation plate disposed between the linear polarization layer and the flexible display panel.
