Method for manufacturing colorless transparent glass-fabric reinforced polyimide film for flexible displays

Abstract

A method of manufacturing a colorless transparent polyimide film having reinforced glass fabric for flexible displays, suitable for use in increasing optical transmittance of a polyimide substrate having reinforced glass fabric for flexible displays. This method enables the glass fabric and the colorless transparent polyimide film to be matched in refractive index when the glass fabric is reinforced in the colorless transparent polyimide film to enhance thermal and mechanical properties of a substrate for flexible displays, thus satisfying high optical transparency and optical transmittance of 85% or more, required of a substrate for flexible displays, and thereby the colorless transparent polyimide film having reinforced glass fabric can be used as a substrate for flexible displays.
