Abstract: A base carrier configured to carry a flexible base of a flexible display panel is provided. The flexible display panel includes a display region and a circuit bonding region. A surface of an area of the base carrier corresponding to the display region is smooth, and a surface of an area of the base carrier corresponding to the circuit bonding region is formed with a plurality of micro-grooves. The structure of the base carrier is such that when the flexible base is separated from the base carrier, the amount of laser required for peeling in each of the display region and the circuit bonding region are the same and such that the base carrier can be separated from the flexible display panel by performing the laser scanning once, which simplifies the processes.
