Display apparatus, manufacturing method of display apparatus, and electronic device
View Patent ↗A display apparatus includes: 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 and transmitting a signal to drive the respective pixel portions; connection pads provided on the outside of the display region and serving as input portions that 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.
1. A display apparatus comprising:
a display region including a plurality of pixel portions;
wires connected to respective pixel portions within the display region from an outside of the display region and providing a signal to drive the respective pixel portions;
connection pads provided on the outside of the display region, the connection pads electrically connected with the wires and serving as input portions via which the signal is provided to the wires;
switch elements provided on the outside of the display region and connected in a middle of the wires; and
a light shielding covering portion that is formed over the switch elements to shield the switch elements from light, and that is also formed on the connection pads such that the light shielding covering portion covers the connection pads and is electrically connected to the connection pads.
2. The display apparatus according to claim 1 , wherein:
each of the plurality of pixel portions includes an organic electroluminescence layer interposed between an anode electrode and a cathode electrode, and
the light shielding covering portion is made of a material that is same as a material from which the anode electrode is made of.
3. The display apparatus according to claim 1 , wherein the switch elements are elements provided to protect transistors that drive the respective pixel portions.
4. The display apparatus according to claim 1 , wherein the switch elements are elements used during a performance test of transistors that drive the respective pixel portions.
5. The display apparatus according to claim 1 , wherein the wires are scan lines to provide a signal to sequentially select transistors that drive the respective pixel portions.
6. The display apparatus according to claim 1 , wherein the wires are power supply control lines to provide a control signal of a power supply voltage to transistors that drive the respective pixel portions.
7. The display apparatus according to claim 1 , wherein the wires are signal lines to provide a video signal to transistors that drive the respective pixel portions.
8. An electronic device comprising:
a display apparatus in a main body casing, the display apparatus including
