ABSTRACT:
An active matrix drive organic EL display panel comprising an organic TFT with a configuration that prevents the occurrence of current leak, and a manufacturing method thereof are proposed. The organic EL display panel comprises: a substrate; an organic EL element comprising in order from the substrate, a first display electrode, an organic functional layer and a second display electrode; and an organic TFT for driving and controlling the organic EL element comprising in order from the substrate a gate electrode, a gate insulation film, source/drain electrodes, and an organic semiconductor layer. The organic EL display panel further comprises: a first bank having a first window section for demarcating a light emitting region on which the organic functional layer is provided on the first display electrode and a second window section demarcating a transistor region on which the organic semiconductor layer is provided between the source/drain electrodes; and a second bank located in the perimeter of the second window section and protruding in a direction that intersects with the main surface of the substrate.
