POLYIMIDE FILM COMPRISING TWO OR MORE FILLERS WITH DIFFERENT PARTICLE DIAMETERS AND ELECTRONIC APPARATUS COMPRISING SAME

摘要

The present invention provides a polyimide film comprising inorganic-based fillers, the inorganic-based fillers comprising: a first filler group having a particle diameter (D50) falling within the range of 2-2.7 ㎛; and a second filler group having an average particle diameter (D50) falling within the range of 1-1.7 ㎛, wherein each of the first and second filler groups satisfies relational expression 1, 0.7 ≤ (D90-D10)/(D50) ≤ 1.2, with respect to the particle diameter.
