THE MANUFACTURING METHOD AND SEALING MATERIALS FOR DISPLAY DEVICE THAT HAS BENN GLASS TRANSITION TEMPERAURE IS UNDER 300°C

摘要

PURPOSE: A sealing material for a display device is provided to ensure strong water resistance and high transmittance and homogenization, to be molten at a low temperature, and to prevent crystallization. CONSTITUTION: A sealing material for a display device with a transition point of 300 °C or less comprises 35~55 wt% P2O5, 1~5 wt% RO2(wherein, R=Zr, Ti), 1~5 wt% R2O3(wherein, R=B, Al, Bi, La), 1-5 wt% RO(wherein, R=Ca, Ba, Zn), and the remaining amount of additives. The additives are prepared by adding sucrose as a reductant to a glass frit in a ratio of 1:0.01~0.1.
