Abstract | The present invention relates to a method for manufacturing a display panel which decreases defects in manufacturing the display panel. The method for manufacturing the display panel comprises the steps of: forming a circuit element layer including a transistor on a plurality of cell areas of a first working substrate, wherein each of the cell areas includes a hole area on which at least one first sub-opening groove, on which the circuit element layer is not formed, is arranged; forming a display element layer including a light emitting element on the plurality of cell areas; removing at least one inorganic layer of the display element layer formed in the first sub-opening groove by stamping to form a second sub-opening groove; coupling the first working substrate to a second working substrate to form a working panel; and cutting the working panel into portions corresponding to the plurality of cell areas to complete the display panel.
표시패널의 제조방법은, 제1 작업기판의 복수의 셀 영역들에 트랜지스터를 포함하는 회로 소자층을 형성하고, 각 셀 영역은 상기 회로 소자층이 형성되지 않는 적어도 하나의 제1 서브 개구홈이 배치된 홀 영역을 포함하는 단계; 상기 복수의 셀 영역들에 발광소자를 포함하는 표시 소자층을 형성하는 단계; 스탬핑 공정을 통해 상기 제1 서브 개구홈에 형성된 상기 표시 소자층 중 적어도 하나의 무기막을 제거하여 제2 서브 개구홈을 형성하는 단계; 상기 제1 작업기판에 제2 작업기판을 결합하여 작업패널을 형성하는 단계; 및 상기 작업패널을 상기 복수의 셀 영역들에 대응하는 부분들로 절단하여 표시패널을 완성하는 단계를 포함한다. |
