본 발명에 따른 헤드업 디스플레이용 광학 기능 필름(10)은, (A) 2층 이상의 위상차층(101)과 (B) 접착층(102)을 구비한다. 접착층(102)은, 적어도 1층의 위상차층(101)에 인접하고, 또한 접착층(102)의 굴절률과 접착층(102)에 인접하는 위상차층(101)의 진상축 방향에 있어서의 굴절률의 차의 절대값이 0.060 미만이다.
An optical functional film for a head-up display (10) according to the present invention includes (A) two or more phase difference layers (101) and (B) an adhesive layer (102). The adhesive layer (102) is adjacent to at least one phase difference layer (101), and an absolute value of difference between a refractive index of the adhesive layer (102) and a refractive index of the phase difference layer (101) adjacent to the adhesive layer (102) in a direction of a fast axis is less than 0.060.
