Abstract: The present invention relates to a release layer for a metal foil with carrier and a metal foil with carrier including the release layer. The release layer is designed for easy removal of the carrier and includes one or more nitrogenous heterocyclic compounds and one or more inorganic compounds containing at least one metal selected from the group consisting of nickel, molybdenum, cobalt, phosphorus, manganese, and iron.

Abstract: Provided are vertical-type organic light-emitting transistors and organic LED illumination apparatuses. The organic LED illumination apparatus includes gate electrode lines that are disposed parallel to each other with predetermined gaps on a substrate; a gate insulating layer covering the gate electrode lines on the substrate; a plurality of first electrode lines that are disposed to overlap or perpendicularly cross the gate electrode lines on the gate insulating layer; a first charge transport layer covering the first electrode lines on the gate insulating layer; a plurality of active layers arranged in a matrix array facing the first electrode lines on the first charge transport layer; a second charge transport layer covering the active layers on the first charge transport layer; and a plurality of second electrode lines that are perpendicularly disposed with respect to the first electrode lines and traverse the active layers on the second transport layer.
