The present invention relates to a substrate insulating layer composition comprising a soluble Liquid Crystal Thermosetting Oligomer, a metal alkoxide, graphene oxide, and short fibers, an insulating material using the same, and a substrate. The insulating layer composition according to the present invention can effectively lower the coefficient of thermal expansion by the addition of metal alkoxide and graphene oxide, by using this as an insulating material of the substrate to minimize the dimensional deformation by heat can be produced a substrate with improved thermal safety In addition, the addition of short fibers can provide a substrate material with greatly increased strength and rigidity. |
