Abstract
Embodiments of the present disclosure provide a phase film substrate, a manufacturing method thereof, and a display device. The phase film substrate includes a base film and a liquid crystal polymer layer on the base film. The liquid crystal polymer layer includes a plurality of strip-shaped liquid crystal sub-layers arranged in parallel in a first direction of the base film. Widths of the plurality of strip-shaped liquid crystal sub-layers in the first direction gradually decrease from a center of the base film to edges of the base film in the first direction, and the first direction is a direction in which the phase film substrate receives force and extends when it is attached to a display panel.
