An SED is formed by sealing a front-side substrate provided with an image display area having a fluorescent layer on its inside surface, and a back-side substrate provided with a plurality of electron-emitting elements and driving wires for driving the electron-emitting elements, through a rectangular frame-like sidewall. On the outside of the image display area of the front-side substrate, frame-like power supply wiring to apply a high voltage to the image display area through a metal back is formed. In the area of the back-side substrate opposite to the power supply wiring, a bypass member to function as a lightning rod is provided electrically independent of a lower wire.

A front substrate of an image display device has a phosphor screen and a metal back layer superposed on the phosphor screen. A plurality of electron emitting elements which emit electrons toward the phosphor screen are located on a rear substrate opposed to the front substrate. The metal back layer has a region which corresponds to the phosphor screen and is divided by gaps g1 in a first direction and gaps g2 in a second direction perpendicular to the first direction such that there are relations g1

An image display system produces a color image by arranging a color shutter capable of time-divisionally switching a plurality of colors to be displayed, in front of a monochrome image display. This image display system comprises: a self-luminous image display part for time-divisionally displaying monochrome images corresponding to three primary colors; and a color display part for time-divisionally coloring and outputting the monochrome images which formed on the side of the light outgoing surface of the self-luminous image display part and which correspond to the three primary colors. The color display part further comprises: a liquid crystal cell driven by carrying out an optical switching on the basis of the inversion between positive and negative polarities; a transparent electrode formed by dividing the liquid crystal cell into a plurality of parts; and a liquid crystal color shutter capable of optionally setting display colors for a plurality of display regions by means of the transparent electrode, the liquid crystal color shutter displaying different display colors for at least two display regions in an optional time in a driving condition.

A vacuum envelope of a display apparatus includes a rear plate, a face plate opposing the rear plate, and a side wall interposed between the rear and face plates. A phosphor screen is formed on the inner surface of the face plate. A plurality of electron-emitting elements are provide on the inner surface of the rear plate, to emit electrons to the phosphor screen. A reinforced glass plate is provided, opposing the outer surface of the face plate. A resistive layer is provided between the reinforced glass plate and the face plate. The resistive layer has a sheet resistance of 10 &OHgr;/□ or more and is set at an anode potential.

The evacuated envelope of an image display apparatus has a rear substrate, a front substrate opposing the rear substrate, and a sidewall interposed between the rear and front substrates. A phosphor screen is formed on the inner surface of the front substrate. Electron-emitting elements are provided on the rear substrate. An indium layer is formed on a sealing surface lying between the front substrate and the sidewall. When the indium layer is heated and melted in a vacuum atmosphere, the front and rear substrates are sealed to each other, with the sidewall interposed between them.

A front substrate, which forms an image display device, includes a metal back layer which is laid over a phosphor screen and is composed of a plurality of divisional electrodes. A first gap is provided between neighboring divisional electrodes in a first region on the front substrate. A second gap, which is greater than the first gap, is provided between neighboring divisional electrodes in a second region which is located at a periphery of the first region. The second region includes, at least at a part thereof, a region having a lower resistance than the first region.
