Abstract: A wiring board includes a substrate including a first main surface, a second main surface, a side surface, and an inclined surface connecting the first main surface and the side surface, and side wiring on the first main surface, the inclined surface, and the side surface. The side wiring has a content of conductive particles greater than a content of an insulating component, and the wiring has a thickness equal to a thickness of at least one of the conductive particles in a first corner between the first main surface and the inclined surface and in a second corner between the inclined surface and the side surface.

Abstract: A display device includes a substrate including a first surface and a second surface opposite to the first surface, a display on the first surface, a first wiring pad located on the second surface and electrically connected to the display, an external connection terminal on the second surface, connection wiring located on the second surface and electrically connecting the first wiring pad and the external connection terminal, and a dummy conductor being a protrusion on the second surface. The protrusion overlaps none of the first wiring pad, the external connection terminal, and the connection wiring in a plan view.

Abstract: A display device includes a substrate including a first surface, a side surface, and a second surface opposite to the first surface, a pixel unit located on the first surface and including a light emitter, a first connection pad adjacent to an edge on the first surface and electrically connected to the pixel unit, a second connection pad adjacent to the edge on the second surface, and a side wire extending from the first surface through the side surface to the second surface and connecting the first connection pad and the second connection pad. The first connection pad and the second connection pad have different sizes.
