The present invention provides a liquid crystal display of which the flexibility is secured, a manufacturing process is simplified, and a cost is reduced, and a method for manufacturing the same. According to an embodiment of the present invention, the method for manufacturing a liquid crystal display comprises the steps of: forming a polymer thin film layer on a substrate; forming a thin film transistor (TFT) substrate on the polymer thin film layer; forming a TFT array on the TFT substrate; forming an upper polarizing plate on the TFT substrate on which the TFT array is formed; applying a laser to the polymer thin film layer to remove a portion of the polymer thin film layer and the substrate; bonding an adhesive layer to a rear surface of the polymer thin film layer from which the substrate is separated; and attaching the polymer thin film layer, to which the adhesive layer is bonded, to a lower polarizing plate. 본 발명의 일 실시예에 따른 액정 표시 장치의 제조 방법은 기판 위에 고분자 박막층을 형성하는 단계, 상기 고분자 박막층 위에 박막 트랜지스터(TFT) 기판을 형성하는 단계, 상기 박막 트랜지스터 기판 위에 박막 트랜지스터 어레이(array)를 형성하는 단계, 상기 박막 트랜지스터 어레이가 형성된 상기 박막 트랜지스터 기판 상에 상부 편광판을 형성하는 단계, 상기 고분자 박막층에 레이저를 가하여 상기 고분자 박막층의 일부 및 상기 기판을 제거하는 단계, 상기 기판이 분리된 고분자 박막층 배면에 점착층을 부착하는 단계, 상기 점착층이 부착된 고분자 박막층과 하부 편광판을 합착하는 단계를 포함한다.
