The present invention discloses a method for manufacturing a liquid crystal protection film, capable of preventing delamination between a tempered glass and a film by securely binding the tempered glass with the film. The method includes: a tempered glass printing step (S1) of forming a printing unit (14) by digitally printing a pattern, a letter or a photograph on a bezel area (13) of a tempered glass (10) having a flat part (11) and a curved part (12) formed at an edge of the flat part (11); a film printing step (S2) of forming a monochrome printing section (22) by performing silk printing on a bezel region (21) of a first film (20) in a single color; a first binding step (S3) of binding the tempered glass (10) in which the printing unit (14) is formed in the bezel region (13) by the tempered glass printing step (S1) with the first film (20) in which the monochrome printing section (22) is formed in the bezel region (21) by the film printing step (S2) together with a curved portion (12) provided on an edge of the tempered glass (10); and a second binding step (S4) of binding a second film (30) with the first film (20) bound with the tempered glass (10) in the first binding step (S3) such that the second film (30) covers the flat part (11) except for the curved part (12) of the tempered glass (10). 본 발명은 액정 보호필름 제조방법이 개시되는 것으로, 평면부(11)와 상기 평면부(11)의 가장자리에 곡면부(12)를 갖는 강화유리(10)의 베젤영역(13)에 문양이나 모양 또는 글씨 또는 사진을 디지털프린팅하여 프린팅부(14)를 형성하는 강화유리프린팅단계(S1); 제1필름(20)의 베젤영역(21)에 단색의 색상으로 실크인쇄하여 단색인쇄부(22)을 형성하는 필름인쇄단계(S2); 상기 강화유리프린팅단계(S1)에 의해 베젤영역(13)에 프린팅부(14)가 형성된 강화유리(10)와 상기 필름인쇄단계(S2)에 의해 베젤영역(21)에 단색인쇄부(22)가 형성된 제1필름(20)을 합지하되 강화유리(10)의 가장자리에 구비되는 곡면부(12)를 포함하여 합지하는 1차합지단계(S3)와; 상기 1차합지단계(S3)에 의해 강화유리(10)와 합지된 제1필름(20)에 제2필름(30)을 2차 합지하되 강화유리(10)의 곡면부(12)를 제외한 평면부(11)를 덮어 포설하도록 제2필름(30)을 합지하는 2차합지단계(S4)로 구비되어 이루어진다.
