Abstract
(EN)
A polarizer (200) comprises a first uniaxial optical film (210), a second uniaxial optical film (220) and a polarization layer (230). The second uniaxial optical film is provided above the first uniaxial optical film. The second uniaxial optical film has an extraordinary refractive index greater than an ordinary refractive index of the first uniaxial optical film. The second uniaxial optical film comprises a plate portion (221) and multiple prism portions (222) formed at one side of the plate and arranged at intervals. The multiple prism portions are received in the first uniaxial optical film. The prism portion is selected from one of a triangular prism structure and a triangular pyramidal structure. The polarization layer is attached to one side of the plate portion away from the prism portions (222).

La présente invention concerne un polariseur (200) qui consiste en un premier film optique uniaxial (210), en un second film optique uniaxial (220) et en une couche de polarisation (230). Le second film optique uniaxial est disposé au-dessus du premier film optique uniaxial. Le second film optique uniaxial présente un indice de réfraction extraordinaire supérieur à un indice de réfraction ordinaire du premier film optique uniaxial. Le second film optique uniaxial comprend une partie plaque (221) et de multiples parties prismes (222) formées sur un côté de la plaque et agencées à des intervalles. Les multiples parties prismes sont reçues dans le premier film optique uniaxial. La partie prisme est sélectionnée parmi une structure de prisme triangulaire et une structure pyramidale triangulaire. La couche de polarisation est fixée à un côté de la partie plaque à l'opposé des parties prismes (222).
