According to the method in the embodiments of the present disclosure, the layer of flexible display devices may be formed on the glass support plate 3 at first. Next, a portion of each layer at the cutting region 1 between two adjacent flexible display devices may be removed through an etching process, so as to separate the flexible display devices from each other. Finally, each etched flexible display device may be removed from the glass support plate 3 through an LLO process, so as to obtain a plurality of flexible display devices separated from each other. Hence, during the manufacture of the flexible display device using the method in the embodiments of the present disclosure, the display devices may be separated from each other through an etching process, and as compared with the related art where a laser cutting process is adopted, it is able to provide a smaller cutting width, and accurately control a bezel of each display device. In a word, through the method in the embodiments of the present disclosure, it is able to provide the product with an ultra-narrow bezel while ensuring the quality of the display device.

In some embodiments of the present disclosure, the process of removing the portion of each layer at the cutting region 1 through an etching process may be performed at any appropriate time according to the practical need. For example, the portion of each layer at the cutting region 1 may be removed through an etching process after the formation of the layer covering the cutting region 1. Also, the portions of at least two layers at the cutting region 1 may be removed through an etching process after the formation of the at least two layers covering the cutting region 1.
