Title
(EN) OPTICAL LAMINATE
(FR) STRATIFIÉ OPTIQUE
(KO) 광학 적층체
Abstract
(EN)
The present application relates to an optical laminate and a use thereof. The optical laminate of the present application is excellent in blocking ultraviolet rays, particularly ultraviolet rays including a blue light region of 380 nm or more. Especially when applied to an organic light emitting device, the optical laminate of the present application can minimize shortening of the lifetime of a blue light source in the organic light emitting device. The optical laminate of the present application has little change in color values and can exhibit excellent durability while not affecting optical properties. The optical laminate is particularly suitable when used in an organic light emitting device.

La présente invention concerne un stratifié optique et une utilisation associée. Le stratifié optique de la présente invention est excellent en termes de blocage de rayons ultraviolets, en particulier de rayons ultraviolets comprenant une région de lumière bleue de 380 nm ou plus. En particulier lorsqu'il est appliqué à un dispositif électroluminescent organique, le stratifié optique de la présente invention peut réduire au minimum le raccourcissement de la durée de vie d'une source de lumière bleue dans le dispositif électroluminescent organique. Le stratifié optique de la présente invention a peu de changement des valeurs de couleur et peut présenter une excellente durabilité, sans affecter les propriétés optiques. Le stratifié optique est particulièrement approprié lorsqu'il est utilisé dans un dispositif électroluminescent organique.
