Beschreibung
Zusammenfassung:	The present invention addresses the problem of providing a polyimide and the like which has excellent transparency and high heat-resistance, wherein the polyimide and a barrier film and/or substrate laminated on the polyimide are not peeled off even during a high-temperature process exceeding 400 DEG C, and yellowing does not occur. The problem is solved by means of a polyamic acid composition including: a polyamic acid having a specific structure; a plasticizer; and a phenolic compound.
