Abstract
(EN)
Provided are: an optical film with which a reduction in thickness can be achieved, and with which the adhesion between a first functional layer and a second functional layer can be improved; a polarization plate comprising such an optical film; and an image display device. According to one embodiment of the present invention, an optical film 10 comprises, in order, a light-transmitting substrate 11, a first functional layer 12, and a second functional layer 13. At least one of the first functional layer 12 and the second functional layer 13 includes an ultraviolet absorbing agent. The optical film further comprises a mixed layer 14 that is provided between the first functional layer 12 and the second functional layer 13, that is adjacent to the first functional layer 12 and the second functional layer 13, and that includes a component of the first functional layer 12 and a component of the second functional layer 13. The total film thickness of the first functional layer 12, the second functional layer 13, and the mixed layer 14 is 1-10 μm, and the proportion of the film thickness of the mixed layer 14 relative to the total film thickness of the first functional layer 12, the second functional layer 13, and the mixed layer 14 is 0.6-40%.

L'invention concerne : un film optique avec lequel une réduction d'épaisseur peut être obtenue, et avec lequel l'adhérence entre une première couche fonctionnelle et une seconde couche fonctionnelle peut être améliorée ; une plaque de polarisation comprenant un tel film optique ; et un dispositif d'affichage d'image. Selon un mode de réalisation de la présente invention, un film optique 10 comprend, dans l'ordre, un substrat de transmission de lumière 11, une première couche fonctionnelle 12, et une seconde couche fonctionnelle 13. La première couche fonctionnelle 12 et/ou la seconde couche fonctionnelle 13 comprennent un agent absorbant les ultraviolets. Le film optique comprend en outre une couche mixte 14 qui est disposée entre la première couche fonctionnelle 12 et la seconde couche fonctionnelle 13, qui est adjacente à la première couche fonctionnelle 12 et à la seconde couche fonctionnelle 13, et qui comprend un composant de la première couche fonctionnelle 12 et un composant de la seconde couche fonctionnelle 13. L'épaisseur totale de film de la première couche fonctionnelle 12, de la seconde couche fonctionnelle 13 et de la couche mixte 14 est de 1 à 10 µm, et la proportion de l'épaisseur de film de la couche mixte 14 par rapport à l'épaisseur de film totale de la première couche fonctionnelle 12, de la seconde couche fonctionnelle 13, et de la couche mixte 14 est de 0,6 à 40 %.
