Abstract
(EN)
The present application relates to a polarizing structure, comprising a pressure-sensitive adhesive layer which has a low refractive index and is provided with multiple grooves, and an optical compensation film which has a high refractive index. Multiple convex structures that match the grooves are provided on the optical compensation film. Also provided is a display device.
(FR)
La présente invention concerne une structure de polarisation, comprenant une couche d'adhésif sensible à la pression qui présente un faible indice de réfraction et qui est pourvue de multiples rainures, et un film de compensation optique qui présente un indice de réfraction élevé. De multiples structures convexes qui correspondent aux rainures sont situées sur le film de compensation optique. L’invention concerne également un dispositif d’affichage.
