Abstract
A conductive member is provided, surrounding a terminal, on a substrate so that a portion of the conductive member is positioned between wiring and the terminal. The conductive member includes, at an inner edge thereof, multiple portions whose distances from the terminal are different. The multiple portions include a portion whose distance from the terminal is shorter than that of a portion among the plurality of portions that is closest to the wiring.
Claims18
A display panel comprising:
- an insulating substrate;
- an electron-emitting device and wiring connected to the electron-emitting device, the electron-emitting device and the wiring being positioned on the substrate;
- an anode and a light-emitting member facing the electron-emitting device at a distance from the substrate;
- a terminal that penetrates through the substrate and is electrically connected to the anode;
- and
- a conductive member whose part is positioned in a region between the wiring and the terminal, the conductive member being positioned on the substrate so as to surround the terminal,
- wherein the terminal is arranged to be set to an anode potential, and the conductive member is arranged to be set to a potential, which is lower than the anode potential,
- wherein the conductive member includes, at an inner edge thereof, a plurality of portions whose distances from the terminal are different, and the plurality of portions include a portion whose distance from the terminal is shorter than that of a portion that is closest to the wiring among the plurality of portions, and
- wherein the conductive member includes a lead-out portion that extends from the inner edge toward an edge of the substrate, and the lead-out portion extends at a greater distance from the wiring than that of the portion that is closest to the wiring.
