Abstract

In a composition of forming a passivation layer, the composition includes about 30 to about 60 percent by weight of a mixed polymer resin formed by blending polyamic acid and polyhydroxy amide, about 3 to about 10 percent by weight of a photoactive compound, about 2 to about 10 percent by weight of a cross-linking agent and an organic solvent. The passivation layer formed by using the composition has superior mechanical and physical properties, in which disadvantages of polyimide and polybenzoxazole are compensated by mixing both materials.
