Claim Text:
1. A method of cutting an organic light-emitting diode (OLED) display panel, comprising: forming a plurality of OLEDs over a lower mother substrate, wherein the OLEDs are divided into a plurality of groups; forming a plurality of sealant lines over at least one of an upper mother substrate or the lower mother substrate such that each sealant line surrounds a corresponding group of the OLEDs; forming a plurality of assistance sealant lines, each of which is formed between two neighboring sealant lines; attaching the upper mother substrate to the lower mother substrate with the sealant lines and the assistance sealant lines; irradiating each of the assistance sealant lines together with the two neighboring sealant lines via a laser, wherein each of the assistance lines and the two neighboring sealant lines are irradiated with light having a power that gradually decreases from a center axis of the light to the edge of the light; and cutting the upper mother substrate and the lower mother substrate along the assistance sealant lines, wherein each of the assistance sealant lines is formed to: i) be spaced apart from the two neighboring sealant lines adjacent to the lower mother substrate and ii) contact the two neighboring sealant lines adjacent to the upper mother substrate, wherein the assistance sealant lines are formed of a different material than that of the sealant lines, and wherein the sealant lines include frit and each of the assistance sealant lines includes more frit than each of the sealant lines.
