Abstract
Row-directional wires, column-directional wires having a resistance higher than that of the row-directional wires, and electron-emitting devices are disposed on a substrate. The electron-emitting devices and the column-directional wires are each connected via a resistor element. The resistor element is provided with a local fuse portion that is easier to fuse than the other portion. The fuse portion is provided closer to the row-directional wire than to the column-directional wire.
Claims9
An electron source substrate comprising:
- a substrate;
- a row-directional wire disposed on the substrate;
- a column-directional wire disposed on the substrate;
- an electron-emitting device a first end of which is connected to the row-directional wire and a second end of which is connected to the column-directional wire via a resistor element, and to which operating voltage is applied through the row-directional wire and the column-directional wire,
- wherein the resistance of the row-directional wire is lower than the resistance of the column-directional wire;
- and
- wherein the resistor element includes a local fuse portion that is easier to fuse than the other portion, the fuse portion being disposed closer to the row-directional wire than to the column-directional wire.
