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 (11)

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 includes a gate, a source and a drain, is electrically connected with the conductive film;

an organic EL element layer provided on the TFT circuit layer and including an organic EL element; and

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

wherein the organic EL display device has a display area, in which pixels are arranged, and a frame area, and

wherein the conductive film overlaps the display area in plan view.

2. The organic EL display device according to claim 1 , further comprising a terminal at an opposite side of the TFT circuit layer through the conductive film, the terminal being connected with the conductive film.

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 , further comprising an electronic component which is a driving integrated circuit element to control the organic EL element and includes the terminal.
