Abstract
A glass light-guiding plate which has high-temperature stability and is advantageous in being manufactured in a slim profile is provided. The glass light-guiding plate includes a glass plate including 75 to 85 wt % SiO2, 5 to 20 wt % B2O3, 1 to 5 wt % Al2O3, 3 to 8 wt % R2O (here, R is at least one of Li, Na, and K), and Fe2O3<0.0025 wt %.
