Polyimide Film Comprising Two or More Fillers Having Different Particle Diameter and Electronic Device Comprising the Same

摘要

The present invention includes an inorganic filler comprising a first group of fillers having a particle diameter (D50) in the range of 2 μm to 2.7 μm and a second group of fillers having an average particle diameter (D50) in the range of 1 μm to 1.7 μm, Provided is a polyimide film satisfying the relational expression 1: 0.7 ≤ (D90-D10)/(D50) ≤ 1.2 for each particle size of the first filler group and the second filler group.
