A flexible display panel, and particularly, to a flexible display panel which is bendable, not an existing glass substrate, a fabrication method thereof, and an image display terminal unit using a flexible display panel are provided.In the case of the flexible display panel, the fabrication method, and the image display terminal unit, the flexible display panel is implemented with a plastic substrate, rather than the conventional glass substrate, and a portion of the non-active area of the display panel is cut to form a cutout portion to insert modules of the image display terminal unit into the cutout portion to thus reduce a receiving space of the lower housing, thereby minimizing a width of the bezel region.
