Abstract

A display apparatus including: a display region provided with a plurality of pixel portions; wires installed to the respective pixel portions within the display region from an outside of the display region for transmitting a signal to drive the respective pixel portions; connection pads provided on the outside of the display region and serving as input portions to provide the wires with a signal while electrically conducting with the wires; switch elements provided on the outside of the display region in a middle of the wires; and a light shielding covering portion shielding the switch elements from light and formed to cover the connection pads while electrically conducting with the connection pads.

Claims (16)

1. A display apparatus having, in plan view, a display region including at least one pixel, the display apparatus comprising:

(a) a plurality of switching elements on a substrate;

(b) a planarizing layer on the switching elements;

(c) a shielding layer overlaying the switching elements;

(d) a connection pad outside of the display region;

(e) an anode electrode, a wire, and an insulating layer on the planarizing layer with the insulating layer having a first opening via which the anode electrode is exposed and a second opening via which the wire is exposed, the anode electrode and the shielding layer being made of a same material; and

(f) an organic electroluminescence layer and a cathode electrode on the anode electrode, in this order.

2. The display apparatus of claim 1 , wherein:

the switching elements are located outside of the display region;

scan lines extend between the switching elements; and

the light shielding layer overlays the switching elements at both end sides of the scan lines outside of the display region.

3. The display apparatus of claim 1 , wherein the switching elements are part of a protection circuit.

4. The display apparatus of claim 1 , wherein the switching elements are part of a test switch circuit.

5. The display apparatus of claim 1 , wherein the same material of the anode electrode overlays the connection pad.

6. The display apparatus of claim 5 , wherein the same material of the anode electrode is connected to the connection pad.

7. The display apparatus of claim 1 , wherein the anode electrode and the wire are on the insulating layer.
