WIRING SUBSTRATE AND DISPLAY DEVICE INCLUDING THE SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 17963659 titled 'WIRING SUBSTRATE AND DISPLAY DEVICE INCLUDING THE SAME
Simplified Explanation
The patent application describes a display device that includes a first substrate with a display area and a pad area, conductive layers, a via layer, electrodes, insulating layers, light-emitting elements, and connecting electrodes.
- The display device includes a first substrate with a display area and a pad area.
- The first substrate has conductive layers with wires and conductive patterns in the display area and the pad area.
- A via layer is present on the conductive layers.
- The display area has first and second electrodes that are spaced apart from each other.
- A first insulating layer is present on the first and second electrodes.
- Light-emitting elements are located on the first and second electrodes and the first insulating layer.
- A first connecting electrode is on the first electrode and in contact with the light-emitting elements.
- A second connecting electrode is on the second electrode and in contact with the light-emitting elements.
- At least one of the conductive layers includes a metal layer made of a copper-silver (CuAg) alloy with a crystal grain size of 140 nm or less.
