PURPOSE: To improve the contrast without impairing the reproducibility of hue of a color display picture image by incorporating Nd2O3, Er2O3, V2O5, CoO, and MnO2 to a compsn. of a silicate glass.

CONSTITUTION: A filter glass contains each coloring component comprising 0.4W4wt% Nd2O3, 0.4W4wt% Er2O3, 0.4W3wt% V2O5, 0.003W0.06wt% CoO, and 0.08W1.2wt% MnO2 basing on 100wt% silicate glass compsn. The glass has high transmittance in the blue (430W470nm), green (540W560nm), and red (610W650nm) region of the visible rays, having also distinct absorption in the intermediate wavelength region and the near ultraviolet region. The silicate glass component consists essentially of SiO2 to which one or plural kinds among Al2O3, B2O3, CaO, MgO, SrO, BaO, ZnO, PbO, Na2O, K2O, Li2O, etc., or further ≥one kind of As2O3 and Sb2O3, etc., are added as a clarifying agent.
