Abstract

An organic EL display device includes an inorganic insulating film including a contact part as an opening where a contact electrode made of a conductive film is exposed, a TFT circuit layer provided on the inorganic insulating film and including a circuit including a thin film transistor, an organic EL element layer provided on the TFT circuit layer and including an organic EL element whose light emission is controlled by the circuit, and a sealing layer covering the organic EL element layer and made of an inorganic insulating material.

Claims (10)

1. An organic EL display device comprising:

a first stack having an inorganic insulating film and a conductive film which has a contact part;

a TFT circuit layer provided on the first stack, the TFT circuit layer includes a circuit including a thin film transistor (TFT) which is electrically connected with the conductive film;

an organic EL element layer provided on the TFT circuit layer and including an organic EL element whose light emission is controlled by the circuit; and

a sealing layer covering the organic EL element layer and including an inorganic insulating material,

wherein a part of the conductive film overlaps the display area in plan view.

2. The organic EL display device according to claim 1 , further comprising an electronic component including a terminal electrically connected to the conductive film in the contact part.

3. The organic EL display device according to claim 1 , further comprising a touch panel on the sealing layer.

4. The organic EL display device according to claim 3 , wherein the touch panel has a substrate provided on the sealing layer via an adhesive layer.

5. The organic EL display device according to claim 2 , wherein the electronic component is a driving integrated circuit element to control the organic EL element.
