1. A flexible display panel, comprising:
a flexible base substrate;
an organic light-emitting functional film on the flexible base substrate;
a top electrode layer on the organic light-emitting functional film;
an encapsulation thin film covering the organic light-emitting functional film and the top electrode layer; and
a via-hole penetrating through the flexible base substrate, the organic light-emitting functional film, the top electrode layer, and the encapsulation thin film;
wherein the flexible base substrate comprising:
a via-hole area for accommodating the via-hole; and
a flexible base substrate area surrounding the via-hole area;
an orthographic projection of the encapsulation thin film on the flexible base substrate is within the flexible base substrate area; and
a pattern of the organic light-emitting functional film is same as a pattern of the top electrode layer.
