The present invention relates to an optical film with dichroic axes in different wavelength bands. The optical film includes: a first substrate; a first polarizer provided on the first substrate and including a first dichroic dye arranged in a first direction; a second polarizer provided in the first polarizer and arranged in a second direction and including a second dichroic dye having a color different from that of the first dichroic dye; and a second substrate disposed on the second polarizer. Accordingly, it is possible to simplify a process and reduce manufacturing cost compared to a conventional color filter. 본 발명은 서로 다른 파장대의 이색성 축을 가진 광학필름에 관한 것으로, 제1기판; 상기 제1기판에 구비되고 제1방향으로 배열된 제1이색성 염료를 포함하는 제1편광부; 상기 제1편광부에 구비되며, 제2방향으로 배열되고 제1이색성 염료와는 다른 컬러의 제2이색성 염료를 포함하는 제2편광부; 및 상기 제2편광부 위에 배치된 제2기판으로 구성된다.
