Abstract:
(EN) A glass sheet for a light diffusion sheet, said glass sheet having two main surfaces facing each other, wherein: the thickness of the glass sheet is 0.3-2.0 mmm inclusive; the average thermal expansion coefficient of the glass sheet at 50-350oC is 60x10-7/K or less; the total light transmittance of the glass sheet at a wavelength of 450 nm, 550 nm or 630 nm is 10-60% inclusive and the sum of the total light transmittance and the total light reflectance at a wavelength of 450 nm, 550 nm or 630 nm is 90% or more; and the glass sheet is formed of a glass which comprises, in terms of mol% on oxide basis, 55-68% of SiO2, 0-9% of Al2O3, 0-19% of B2O3, 4-15% of MgO, 0-4% of BaO and 0-4% of Na2O.
(FR) La présente invention concerne une feuille de verre pour feuille de diffusion de lumière, ladite feuille de verre ayant deux surfaces principales se faisant face l’une l’autre, dans laquelle : l’épaisseur de la feuille de verre est de 0,3 à 2,0 mm inclus ; le coefficient d’expansion thermique moyen de la feuille de verre à 50 à 350oC est de 60 x 10-7/K ou moins ; la transmittance totale de lumière de la feuille de verre à une longueur d’onde de 450 nm, 550 nm ou 630 nm est de 10 à 60 % inclus et la somme de la transmittance totale de lumière et de la réflectance totale de lumière à une longueur d’onde de 450 nm, 550 nm ou 630 nm est de 90 % ou plus ; et la feuille de verre est formée d’un verre qui comprend, en termes de % en mole sur une base d’oxyde, de 55 à 68 % de SiO2, de 0 à 9 % d’Al2O3, de 0 à 19 % de B2O3, de 4 à 15 % de MgO, de 0 à 4 % de BaO et de 0 à 4 % de Na2O.
(JA) 互いに対向する2つの主面を有する光拡散板用ガラス板であって、ガラス板の板厚が0.3mm以上2.0mm以下であり、ガラス板の50℃~350℃における平均熱膨張係数が60×10-7/K以下であり、ガラス板の波長450nm、550nm、630nmの全光線透過率が10%以上60%以下であり、かつ全光線透過率と波長450nm、550nm、630nmの全光線反射率との合計が90%以上であり、ガラス板が酸化物基準のmol百分率表示で、SiOを55~68%、Alを0~9%、Bを0~19%、MgOを4~15%、BaOを0~4%、NaOを0~4%含むガラスからなる、光拡散板用ガラス板。
