Abstract:
(EN) The purpose of the present invention is to provide a glass plate which has a higher internal transmittance of light having a wavelength of about 450 nm, than a conventional glass plate for a light guide plate, and which has optical characteristics suited to a quantum dot display using a blue LED. The present invention pertains to a glass plate containing less than 80 ppm by mass of total iron oxide (t-Fe2O3) in terms of Fe2O3, and more than 0 but less than 1.0 ppm by mass of NiO, more than 0 but less than 1.0 ppm by mass of Cr2O3, and more than 0 but not more than 5.0 ppm by mass of MnO2 on an oxide basis, wherein the proportion of divalent iron (Fe2+) in terms of Fe2O3 in the total iron oxide in terms of Fe2O3 is more than 30%, when expressed as percent by mass.
(FR) Le but de la présente invention concerne une plaque de verre qui présente une transmittance interne plus élevée de la lumière présentant une longueur d'onde d'environ 450 nm qu'une plaque de verre classique pour une plaque de guidage de lumière et qui présente des caractéristiques optiques appropriées à un affichage à points quantiques à l'aide d'une DEL bleue. La présente invention concerne une plaque de verre contenant moins de 80 ppm en masse d'oxyde de fer total (t-Fe2O3) en termes de Fe2O3 et plus de 0 mais moins de 1,0 ppm en masse de NiO, plus de 0 mais moins de 1,0 ppm en masse de Cr2O3 et plus de 0 mais pas plus de 5,0 ppm en masse de MnO2 sur une base d'oxyde, la proportion de fer divalent (Fe2+) en termes de Fe2O3 dans l'oxyde de fer total en termes de Fe2O3 étant supérieure à 30 %, lorsqu'elle est exprimée en pourcentage en masse.
(JA) 本発明は、従来の導光板用ガラス板と比較して、波長450nm近傍における光の内部透過率が高く、青色LEDを用いた量子ドットディスプレイに適した光学特性を有するガラス板を提供することを目的とする。本発明は、Feに換算した全酸化鉄(t-Fe)を80質量ppm未満含有し、酸化物基準で、NiOを0超1.0質量ppm未満、Crを0超1.0質量ppm未満、MnOを0超~5.0質量ppm含有し、且つFeに換算した全酸化鉄中のFeに換算した2価鉄(Fe2+)の割合が、質量百分率表示で30%超であるガラス板に関する。
