Abstract
A flexible touch display module (100) and a touch display device (1000) including the flexible touch display module, the flexible touch display module (100) includes: a flexible display panel (1), a flexible cover plate (2), a linear polarization layer (3), a first retardation plate (4) and a second retardation plate (5). An absorption axis of the linear polarization layer (3) is at an angle of about 90°. The first retardation plate (4) includes a first retardation film (41), and the first retardation film (41) is a liquid crystal layer having a quarter-wavelength retardation. The first retardation film (41) has a major axis and a minor axis in a plane parallel to flexible display panel (1), and an included angle between a direction in which the minor axis of the first retardation film (41) extends and the absorption axis of the linear polarization layer (3) is about 45°.
