Abstract
This invention discloses a linear polarizing layer, a circular polarizing layer, a flexible display apparatus, and preparation methods thereof. The preparation method of a linear polarizing layer according to this invention comprises the steps of: coating a polarizing film precursor material on a flexible base material, wherein the polarizing film precursor material comprises a polarizing material capable of being oriented under a field effect; orientating the polarizing film precursor material in a manner of field induction to allow the direction of orientation thereof to be vertical to the direction of a bending axis of the flexible base material; and curing the polarizing film precursor material to form a linear polarizing layer on the flexible base material.
