Abstract:
(EN) The purpose of the present invention is to provide, as a transparent substrate having a light blocking region and used as a front plate, a transparent substrate provided with an infrared light transmission region and an infrared light non-transmission region in a light blocking region and having the light blocking region where a boundary between these regions cannot be visually recognized. The present invention relates to a transparent substrate having a light blocking region at the periphery of one principal surface of the transparent substrate, and characterized in that the light blocking region includes a first light blocking region and a second light blocking region, the luminous transmittance of the first light blocking region is 0.1-40%, an average transmittance at a wavelength of 800-1000 nm is 65% or more, and the optical density of the second light blocking region is 4 or more, which are measured from the other principal surface of the transparent substrate, and the luminous reflectance of the second light blocking region is 0.1-1%, and an average reflectance R1 at a wavelength of 600-700 nm is 1.5 times or more an average reflectance R2 at a wavelength of 400-600 nm, which are measured from the other principal surface of the transparent substrate, and found except surface reflection at the other principal surface.
(FR) Le but de la présente invention est de fournir, en tant que substrat transparent ayant une région de blocage de lumière et utilisé en tant que plaque avant, un substrat transparent pourvu d'une région de transmission de lumière infrarouge et d'une région de non-transmission de lumière infrarouge dans une région de blocage de lumière et ayant la région de blocage de lumière où une limite entre ces régions ne peut pas être reconnue visuellement. La présente invention concerne un substrat transparent ayant une région de blocage de lumière à la périphérie d'une surface principale du substrat transparent, et caractérisé en ce que la région de blocage de lumière comprend une première région de blocage de lumière et une seconde région de blocage de lumière, la transmittance lumineuse de la première région de blocage de lumière est de 0,1 à 40 %, une transmittance moyenne à une longueur d'onde de 800 à 1000 nm est de 65 % ou plus, et la densité optique de la seconde région de blocage de lumière est de 4 ou plus, qui sont mesurées à partir de l'autre surface principale du substrat transparent, et la réflectance lumineuse de la seconde région de blocage de lumière est de 0,1 à 1 %, et un facteur de réflexion moyen R à une longueur d'onde de 600-700 nm est de 1,5 fois ou plus un facteur de réflexion moyen R à une longueur d'onde de 400 à 600 nm, qui sont mesurées à partir de l'autre surface principale du substrat transparent, et trouvées à l'exception de la réflexion de surface au niveau de l'autre surface principale.
(JA) 本発明は、前面板として使用される遮光領域を有する透明基板として、遮光領域に赤外光透過領域と赤外光不透過領域とを備え、かつ、これらの領域の境界を視認することができない遮光領域を有する透明基板の提供を目的とする。本発明は、透明基板の一方の主面の周辺部に遮光領域を有する透明基板であって、前記遮光領域は、第1の遮光領域と第2の遮光領域を含み、透明基板の他方の主面から測定した、前記第1の遮光領域の視感透過率が0.1~40%であり、波長800~1000nmにおける平均透過率が65%以上であり、前記第2の遮光領域は光学濃度が4以上であり、前記透明基板の他方の主面から測定し、前記他方の主面での表面反射を除いて求められる、前記第2の遮光領域の視感反射率が0.1~1%で、波長600~700nmにおける平均反射率Rが波長400~600nmにおける平均反射率Rの1.5倍以上であることを特徴とする透明基板に関する。
