Abstract
Provided is glass with high temperature stability, a low coefficient of thermal expansion and a high mechanical strength, a light guide plate including the glass to replace the conventional PMMA and metal frame, and fabricating methods thereof. The glass according to the present disclosure is borosilicate glass containing 75˜85 wt % of SiO, 5˜15 wt % of BO, 0˜5 wt % of AlO, RO 1˜7 wt % where R is at least one of Li, Na and K, and <0.005 wt % of FeOand having the redox ratio 0.5 or more. This glass maintains luminance and has an excellent color difference reduction effect when used in a light guide plate.
