In one aspect, the present disclosure provides in some embodiments a method for manufacturing a flexible display device, including: forming a plurality of flexible display devices on a support plate; etching the layer of flexible display devices on the support plate to expose a portion of the support plate at a cutting region, the cutting region being a predetermined region between two adjacent flexible display devices; and removing the layer of flexible display devices from the support plate after the etching process so as to obtain a plurality of flexible display devices separated from each other.

In a possible embodiment of the present disclosure, forming the layer of flexible display devices on the support plate includes: forming a flexible substrate on the support plate; and forming a plurality of layers on the flexible substrate. The cutting region is covered by the flexible substrate and the plurality of layers.

In a possible embodiment of the present disclosure, forming the plurality of layers on the flexible substrate includes forming an etch stop layer. The etch stop layer includes a first barrier pattern and a second barrier pattern arranged at two sides of the cutting region respectively to define an etching width.

In a possible embodiment of the present disclosure, the layer of flexible display devices on the support plate includes a bending region covered by the flexible substrate and the plurality of layers.

In a possible embodiment of the present disclosure, forming the plurality of layers on the flexible substrate includes forming a TFT array layer on the flexible substrate. The TFT array layer includes a gate electrode layer, a source electrode layer and a drain electrode layer.
