ABSTRACT:
A transparent composite composition is provided which comprises an epoxy resin (a) and a glass filler (b) and in which the epoxy resin (a) comprises at least one epoxy resin whose refractive index after curing is lower than the refractive index of the glass filler (b) and at least one epoxy resin whose refractive index after curing is higher than the refractive index of the glass filler (b). The transparent composite composition of the invention has a low coefficient of linear expansion and is excellent in transparency, heat resistance and solvent resistance, among others and, therefore, is judiciously used, for example, in the form of liquid crystal display device substrates and organic EL device substrates (in particular of the active matrix type) and, further, transparent sheets, optical lenses, color filter substrates, solar cell substrates, touch panels, optical devices, optical waveguides, LED sealing materials and so forth.
