Patent number: 8372504Abstract: Provided is a non-hydrolytic transparent composite composition having excellent transparency and heat resistance, and a low thermal expansion coefficient. Particularly, the transparent composite composition includes a glass filler dispersed in a crosslinked transparent resin produced by a non-hydrolytic reaction. The non-hydrolytic transparent siloxane resin is a resin having Si—O (siloxane) bonds, a resin having at least one kind of heterometal bonds, including Si—O bonds, or the resin further containing other ingredients. When the transparent siloxane resin produced by a non-hydrolytic reaction forms a composite in combination with the glass filler, the composite realizes high transparency and heat resistance, as well as a low thermal expansion coefficient. Therefore, the transparent composite composition is useful as a substrate for thin film transistor (TFT) devices, display devices and optical devices.Type: GrantFiled: November 12, 2009Date of Patent: February 12, 2013Assignee: Korea Advanced Institute of Science and TechnologyInventors: Byeong-Soo Bae, Jungho Jin, Seung Cheol Yang, Ji Hoon Ko
