Next, the layer of flexible display devices may be removed from the glass support plate 3 through any appropriate separation processes including, but not limited to, an LLO process, so as to obtain a plurality of flexible display devices separated from each other. Then, a base film may be attached onto the flexible substrate 4 of each flexible display device. In this way, the manufacture process of a flexible display device is completed. Any appropriate separation techniques or processes capable of removing the flexible substrate from the glass support plate may be adopted, and these separation processes may be combined with the etching process according to the embodiment of the present disclosure, so as to achieve a same or similar beneficial effect of the present disclosure, i.e., to provide the product with an ultra-narrow bezel while ensuring the quality of the display device.

As shown in FIG. 1d, the method may include: forming the layer of flexible display devices on the glass support plate 3; etching the layer of flexible display devices on the glass support plate 3 so as to expose a portion of the glass support plate 3 at the cutting region 1, the cutting region 1 being a predetermined region between two adjacent flexible display devices; and after the etching process is completed, removing the respective flexible display devices from the glass support plate 3 so as to obtain a plurality of flexible display devices separated from each other.

When etching the flexible display devices, it is necessary to etch a metal layer, an inorganic material and an organic material included in the plurality of layers through different etching processes, so as to finally expose the portion of the glass support plate 3 at the cutting region 1.
