Zusammenfassung:A light control film manufacturing apparatus according to an embodiment of the present invention comprises: a film supply device for supplying a base film; and a pattern formation mold for applying pressure onto a surface of the base film to form a pattern thereon, wherein the pattern formation mold comprises a main body and a pattern formation structure protruding from the outer surface of the main body and extending in a first direction. The pattern formation structure has a cross section perpendicular to the first direction, wherein the cross section may include: a pair of first intersecting lines, each of which has one end connected to the main body and which have a first contained angle therebetween; and a pair of second intersecting lines, which extend from the other ends of the pair of first intersecting lines, respectively, and have a second contained angle therebetween smaller than the first contained angle. Selon un mode de réalisation, la présente invention concerne un appareil de fabrication de film de commande de lumière qui comprend : un dispositif d'alimentation en film qui permet de distribuer un film de base ; un moule de formation de motif qui permet d'appliquer une pression sur une surface du film de base pour former un motif sur ce dernier, le moule de formation de motif comprenant un corps principal et une structure de formation de motif faisant saillie sur la surface externe du corps principal et se prolongeant dans une première direction. La structure de formation de motif possède une section transversale perpendiculaire à la première direction, la section transversale pouvant comprendre : une paire de premières lignes d'intersection, dont chacune possède une extrémité reliée au corps principal et qui ont un premier angle inclus entre elles ; une paire de secondes lignes d'intersection, qui s'étendent à partir des autres extrémités de la paire de premières lignes d'intersection, respectivement, et ont un second angle inclus entre elles, plus petit que le premier angle inclus. 본 발명 실시예에 따른 광 제어 필름 제조 장치는 베이스 필름을 공급하는 필름 공급 장치 및 상기 베이스 필름의 일면 상에 압력을 가해 패턴을 형성하는 패턴 형성 몰드를 포함하고, 상기 패턴 형성 몰드는 메인 바디 및 상기 메인 바디 외면에 돌출되어 제1 방향으로 연장된 패턴 형성 구조물을 포함하고, 상기 패턴 형성 구조물은 상기 제1 방향에 수직한 단면이, 일단부가 상기 메인 바디와 연결되며 제1 사잇각을 가지는 한 쌍의 제1 교차선 및 상기 한 쌍의 제1 교차선의 타단부에서 각각 연장되며 상기 제1 사잇각보다 작은 제2 사잇각을 가지는 한 쌍의 제2 교차선을 포함할 수 있다.
