Abstract
(EN)
An optical switching element (2) according to the present invention is provided with a drive substrate (10), a transparent substrate (20), a liquid crystal layer (30), and a reflection enhancing film (171). The drive substrate (10) has a pixel region including a plurality of pixel electrodes, a peripheral region disposed outside the pixel region, and a sealed region (40). The transparent substrate (20) has a counter electrode (21). The liquid crystal layer (30) is held between the drive substrate (10) and the transparent substrate (20). The reflection enhancing film (171) is disposed on the entire surface of the drive substrate (10). The reflection enhancing film (171) is configured by laminating one or more dielectric film sets, in each of which two dielectric films having different refractive indexes are laminated as a set. Planarization treatment is performed on a dielectric film of the first layer constituting the reflection enhancing film (171).

La présente invention concerne un élément de commutation optique (2) qui comporte un substrat de commande (10), un substrat transparent (20), une couche de cristaux liquides (30) et un film d'amélioration de réflexion (171). Le substrat d'entraînement (10) a une région de pixels comprenant une pluralité d'électrodes de pixel, une région périphérique disposée à l'extérieur de la région de pixels, et une région scellée (40). Le substrat transparent (20) comporte une contre-électrode (21). La couche de cristaux liquides (30) est maintenue entre le substrat de commande (10) et le substrat transparent (20). Le film d'amélioration de réflexion (171) est disposé sur la totalité de la surface du substrat de commande (10). Le film d'amélioration de réflexion (171) est configuré par stratification d'un ou plusieurs ensembles de films diélectriques, dans chacun desquels deux films diélectriques ayant des indices de réfraction différents sont stratifiés en tant qu'ensemble. Un traitement de planarisation est effectué sur un film diélectrique de la première couche constituant le film d'amélioration de réflexion (171).
