<p>PURPOSE: A composition for insulation layer is provided to lower a thermal expansion coefficient by adding a graphene oxide and a metal alkoxide, minimize size distortion when used as an insulation materials for substrates, and rapidly improve strength and rigidity by adding short fiber. CONSTITUTION: A composition for insulation layer comprises: a soluble liquid crystal thermosetting oligomer, a metal alkoxide, a graphene oxide, and a short fiber. The average molecular weight of the soluble liquid crystal thermosetting oligomer is 500-15,000. The metal of the metal alkoxide is selected from the group comprising Ti, Al, Ge, Co, Ca, Hf, Fe, Ni, Nb, Mo, La, Re, Sc, Si, Ta, W, Y, Zr, and V. The metal alkoxide comprises a substrate for covalent bonding with a thermosetting group contained in the soluble liquid crystal thermosetting oligomer.
