The invention relates to the field of displays. One subject of the invention is a glass composition intended for the production of a substrate for a field-emission display, which has an overall light transmission factor under illuminant D65 (TLD65) that varies from 45 to 80% and is preferably equal to 72% or less, measured for a glass thickness of 2.8 mm, and a blue-gray coloration defined by the following chromatic coordinates:; a*=−4 to +1, preferably −2 to 0; and; b*=−6 to +3, preferably −2 to 0.;The substrates obtained advantageously have a reflection brightness (R) of less than 10 Cd/m2.
