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&#x2dc;85 wt % of SiO, 5&#x2dc;15 wt % of BO, 0&#x2dc;5 wt % of AlO, RO 1&#x2dc;7 wt % where R is at least one of Li, Na and K, and &#x3c;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.

Borosilicate glass, light guide plate comprising the same and fabricating methods thereof

A glass light-guide plate having a small color difference and a manufacturing method thereof are provided. The light-guide plate includes glass containing 70 to 85 wt % of SiO, 5 to 20 wt % of BO, 0 to 5 wt % of AlO, 1 to 7 wt % of RO (here, R is at least one of Li, Na, and K), 0 to 0.005 wt % of FeO, and less than 0.002 wt % of a transition metal oxide for adjusting a color difference.

Glass light-guide plate and manufacturing method thereof

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 % SiO, 5 to 20 wt % BO, 1 to 5 wt % AlO, 3 to 8 wt % RO (here, R is at least one of Li, Na, and K), and FeO&#x3c;0.0025 wt %.
