Abstract

An organic EL display device wherein deterioration of organic transistor performance is reduced, a method for manufacturing such organic EL display device, an organic transistor and a method for manufacturing such organic transistor are provided. The organic EL display device (P1) covers the organic transistor (50), and is provided with a protection film (20) for protecting the organic transistor. The organic EL display device includes a conductive layer (a cathode of an organic EL element (100)) (18) between the protection film (20) and a front plane of the organic transistor (50), and an insulating film (72) formed closer to the front plane side of the organic transistor (50) than the conductive layer (18) for insulating the front plane of the organic transistor (50) from the conductive layer (18).

Description

technical field [0001] The present invention relates to an organic EL display, a method of manufacturing the organic EL display, an organic transistor, and a method of manufacturing the organic transistor. Background technique [0002] Organic transistors are used in a wide variety of applications. For example, it is used as a tool for driving organic EL elements in organic EL displays. [0003] The organic EL element is equipped with an electrode on a substrate and an organic solid layer having at least a light-emitting layer between the electrodes, wherein electrons and electron holes are injected into the light-emitting layer in the organic solid layer from the electrodes on both sides to Light is emitted in the organic light-emitting layer, and high-intensity light emission can be obtained. In addition, it is characterized by a wide selectivity of luminescent colors because the luminescence of organic compounds is used. Therefore, it is expected as a light source and ...
