Beschreibung
Zusammenfassung:	An optical film includes: a base layer; and an optical pattern part disposed inside the base layer. The optical pattern part includes a plurality of optical patterns formed to be completely recessed inside the base layer. The optical pattern has a first axis parallel to a display surface of the optical film and having the longest width on the display surface side of the optical film. The optical pattern has a first region of which the width gradually decreases from the first axis to the top of the optical pattern and a second region of which the width gradually decreases from the first axis to the bottom of the optical pattern. The present invention provides the optical film with a significantly high contrast ratio on side surfaces. 기재층; 및 상기 기재층의 내부에 배치된 광학 패턴부를 포함하는 광학 필름으로서, 상기 광학 패턴부는 상기 기재층의 내부에 완전히 함몰되어 형성된 복수 개의 광학 패턴을 포함하고, 상기 광학 패턴은 상기 광학 필름의 표시면에 대해 평행하고 광학 필름의 표시면 쪽에서 최장 폭을 갖는 제1축을 가지며, 상기 광학 패턴은 상기 제1축으로부터 상기 광학 패턴의 최상부로 갈수록 폭이 점차적으로 감소하는 제1 영역 및 상기 제1축으로부터 상기 광학 패턴의 최하부로 갈수록 폭이 점차적으로 감소하는 제2 영역을 갖는 것인, 광학 필름 및 이를 포함하는 광학표시장치가 제공된다.
