(JA) ディスプレイ装置用結晶化ガラス
Abstract: front page image
(EN)Provided is a cover glass for display devices, which comprises a high-strength and transparent crystallized glass. A crystallized glass for display devices, which has a transmittance (T400nm) of light having a wavelength of 400 nm of more than 10% when the glass is prepared into a thickness of 1 mm, and which is produced by crystallizing a glass comprising, in mol% in terms of oxide contents, 61.5-72% of SiO2, 1-5.5% of Al2O3, 0.5-3% of P2O5, 0.5-3% of ZrO2, 20-35% of Li2O and 0-5% of K2O, wherein the total content of P2O5 and ZrO2 is 1.7-5%.
(FR)La présente invention concerne un verre de recouvrement pour dispositifs d'affichage, qui comprend un verre cristallisé transparent et très résistant. Le verre cristallisé pour dispositifs d'affichage présente une transmittance (T400nm) d'une lumière possédant une longueur d'onde de 400 nm supérieure à 10 % si l'épaisseur du verre est de 1 mm. Le verre cristallisé est produit par la cristallisation d'un verre comprenant, en % en mole en termes de teneurs en oxyde, 61,5 % à 72 % de SiO2, 1 % à 5,5 % d'Al2O3, 0,5 % à 3 % de P2O5, 0,5 % à 3 % de ZrO2, 20 % à 35 % de Li2O et 0 % à 5 % de K2O, la teneur totale en P2O5 et en ZrO2 étant de 1,7 % à 5 %.
(JA) 高強度であり、かつ透明性を有する結晶化ガラスによるディスプレイ装置用カバーガラスの提供。 厚み1mmにおける波長400nmの光の透過率T400nmが10%超であるディスプレイ装置用結晶化ガラスであって、下記酸化物基準のモル%表示で、SiOを61.5~72%、Alを1~5.5%、Pを0.5~3%、ZrOを0.5~3%、LiOを20~35%、KOを0~5%を含有し、PおよびZrOの含有量の合計が1.7~5%であるガラスを結晶化して得られたディスプレイ装置用結晶化ガラス。
