Title (EN) POLARIZER, POLARIZING OPTICAL ELEMENT, LIGHT SOURCE, AND IMAGE DISPLAY DEVICE
(FR) POLARISEUR, ÉLÉMENT OPTIQUE POLARISANT, SOURCE LUMINEUSE ET DISPOSITIF D'AFFICHAGE D'IMAGE
(JA) 偏光子、偏光光学素子、光源および画像表示装置
Abstract: front page image
(EN)There is provided a polarizer capable of increasing the light-extraction efficiency when non-polarized light is converted to light in a specified polarization state. The polarizer is provided with a substrate, a first dielectric part installed on the substrate, and a metal part installed on the first dielectric part, the first dielectric part being installed so as to decrease in size from the substrate toward the metal part.
(FR)La présente invention porte sur un polariseur apte à augmenter le rendement d'extraction de lumière lorsqu'une lumière non polarisée est convertie en lumière dans un état de polarisation spécifié. Le polariseur comporte un substrat, une première partie diélectrique installée sur le substrat et une partie métallique installée sur la première partie diélectrique, la première partie diélectrique étant installée de manière à diminuer en dimension depuis le substrat vers la partie métallique.
(JA) 非偏光を特定の偏光状態の光に変換する際の光の取り出し効率を高くすることが可能な偏光子を提供する。 偏光子は、基板と、基板上に設けられた第1の誘電体部と、第1の誘電体部上に設けられた金属部と、を備え、第1の誘電体部は、基板から金属部に向かって小さくなるように設けられる。
