Abstract

The present invention relates to a polyamic acid polymer composite and a method for producing the same, and more specifically, a polyamic acid polymer composite, which can be applied to display substrate production due to its high transparency and low thermal expansion of glass-level, and a method for producing same. The polyamic acid polymer composite comprises 50 to 99 wt % of a polyamic acid polymer having a repeating unit of Chemical Formula 1; and 1 to 50 wt % of a silica-based particle:
