Abstract
A display apparatus according to the present invention has a plurality of electroconductive layers outside of an image display area. Mutually adjacent ones of the electroconductive layers are electrically connected by a resistor. The resistor has a first region, and a second region which is more separated from the image display area than the first region. The area of the second region per unit length in the direction separating from the image display area is smaller than the area of the first region.
Claims6
An image display apparatus comprising:
- a front substrate having a plurality of phosphor layers and a plurality of electroconductive layers arranged above the plurality of phosphor layers;
- and
- a rear substrate having a plurality of electron-emitting devices for irradiating the plurality of phosphor layers with electrons, wherein
- the front substrate has a resistor arranged outside of an image display area in which the plurality of phosphor layers are disposed on the front substrate,
- mutually adjacent electroconductive layers, among the plurality of electroconductive layers, arranged outside of the image display area, overlap with respectively different portions of the resistor so that said mutually adjacent electroconductive layers are electrically connected to each other via the resistor, and wherein
- the resistor has a first region and a plurality of second regions arranged such that the image display area is closer to the first region rather than to the second regions, and at least one of the second regions has a smaller area than that of the first region, per unit length in a direction of increasing a distance from the image display area, and
- the resistor is arranged to be overlapped with the electroconductive layer at every one of the second regions.
