The invention concerns display screens, in particular emissive displays. The invention concerns a glass composition for making a display screen substrate having an infrared radiation transmission factor measured at 910 nm (TIR910) not more than 40 %, a global light transmission factor under illuminant D65 (TLD65) higher than 40 %, a dominant wavelength (D) rangingfrom 480 to 570 nm and a purity not more than 8 %, measured under a glass thicknessof 2.8 mm, said composition comprising the following coloringagents, in wt. %: Fe2O3:0.4-2 %; FeO:0.1-0.6 %; CoO: 0-200 ppm; Se:0-30 ppm;NiO: 0-1000 ppm;CuO: 0-6600 ppm.
