According to the method for manufacturing the flexible display device in the embodiments of the present disclosure, flexible display devices on a glass support plate may be separated from each other through an etching process, and each flexible display device may be individually attached onto the glass support plate.

According to the method for manufacturing the flexible display device in the embodiments of the present disclosure, it is unnecessary to cut a motherboard into individual display devices through a laser cutting process, therefore the cutting margin is no longer required for the laser cutting process. In addition, through the etching process, it is able to accurately define an etching width at a cutting region, thereby to improve the quality of the display device as well as the yield thereof. Furthermore, through the combination of the etching process and the manufacture process for the functional layers of the flexible display device, it is able to separate the display devices from each other without any additional process, thereby to reduce the manufacture cost.

During the manufacture of the flexible display device, a dry etching process and/or a wet etching process may be adopted for the etching process.

The method for manufacturing the flexible display device in the embodiments of the present disclosure is not limited to performing an etching and removing process after all the layers for the display device have been formed, so the term “flexible display device” intends to cover a completed display device having all the functional layers been formed or any existing functional layer of a display device which is still in a manufacturing process, unless a process state (or stage) has been specified.
