Flexible display device, fabrication method and electronic device thereof

A flexible display device, comprising:

• at least one bending area and a non-bending area, wherein the bending area is provided with a bending axis;
• a flexible display panel having a first surface for displaying images;
• a flexible insulating layer disposed on the first surface of the flexible display panel, wherein in the at least one bending area, the flexible insulating layer is divided into a plurality of flexible insulating blocks, and the flexible insulating layer has a first surface facing the flexible display panel and an opposite second surface;
• and
• a touch control unit disposed on the second surface of the flexible insulating layer, wherein the touch control unit comprises a first touch control electrode layer in direct contact with the flexible insulating layer, and the first touch control electrode layer includes a plurality of first touch control electrodes,
• wherein any one of the plurality of flexible insulating blocks corresponds to at least one of the plurality of first touch control electrodes, and
• in a plane of the first surface and in a direction perpendicular to the bending axis, a gap between any two adjacent flexible insulating blocks overlaps with a gap between two adjacent first touch control electrodes.
