DISPLAY DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18122842 titled 'DISPLAY DEVICE
Simplified Explanation
The patent application describes a display device with multiple layers and contact holes for electrical connections.
- The display device includes a first wiring layer, a first insulating layer, a second insulating layer, and a second wiring layer.
- The first insulating layer is made of an inorganic material, while the second insulating layer is made of an organic material.
- The second insulating layer is thicker than the first insulating layer.
- The contact hole allows electrical connection between the first and second wiring layers.
- The contact hole consists of a first sub-contact hole in the first insulating layer and a second sub-contact hole in the second insulating layer.
- The second insulating layer covers at least part of the edge of the first sub-contact hole.
Original Abstract Submitted
A display device according to an embodiment includes: a first wiring layer disposed on a substrate; a first insulating layer disposed on the first wiring layer and including an inorganic material; a second insulating layer disposed on the first insulating layer, and including an organic material; and a second wiring layer disposed on the second insulating layer and electrically connected to the first wiring layer through a contact hole of the first insulating layer and the second insulating layer. A thickness of the second insulating layer is greater than a thickness of the first insulating layer. The contact hole includes a first sub-contact hole formed in the first insulating layer and a second sub-contact hole formed in the second insulating layer. At least part of at least one edge of the first sub-contact hole is covered with the second insulating layer.
