An image display device includes a front substrate having anodes and phosphors, a rear substrate having plural video signal wirings or lines and plural electron sources each formed on a corresponding one of the video signal wirings or lines, and disposed to face the front substrate with a predetermined spacing between the front and rear substrates and a support member which is sandwiched between the front and rear substrates, surrounds a display area formed therebetween and maintains the predetermined spacing. The support member is includes long-side portions of a uniform width disposed on long sides of the front substrate and short-side portions of a uniform width disposed on short sides of the front substrate. At least the long-side portions are curved convexly toward an outside of the display area.

The present invention provides an image display device which can realize the recycling at a low cost by shortening a disassembling time of a face substrate and a back substrate. In a support frame which is bonded and fixed to a face substrate and a back substrate by way of sealing materials respectively, a cut portion whose spatial region expands from the inside to the outside is integrally formed on an end surface at a corner portion thereof. To outer portions of the cut portions, the sealing materials 10a, 10b are not fixed.

There is disclosed an FED (field emission display) capable of supplying an anode voltage, which is a high voltage, to an anode substrate with high reliability. A high voltage introduction button is sealed to a sealing plate, in which a contact spring is attached to the high voltage introduction button by spot welding. The high voltage introduction button has a flat portion connected to the contact spring, a sealing portion sealed to the glass substrate, and an external terminal to be connected to an external power source. The contact spring contacts an anode terminal of an anode substrate with an appropriate contact pressure, by a spring force from an arm portion of the contact spring. The anode terminal is formed of a conductive film containing metal particles.

A display device includes a back substrate having a plurality of cathode lines, and a plurality of control electrodes, which are insulated from the cathode lines on an inner surface thereof, and a front substrate which is arranged to face the back substrate in an opposed manner with a set distance therebetween, and which has phosphors and an anode which constitute a display region, on an inner surface thereof. Distance holding members are provided for maintaining the set distance between the back substrate and the front substrate inside of the display region. The phosphors are constituted of three colors, and the cathode lines are formed into groups each consisting of three cathode lines corresponding to the three colors. The plurality of cathode lines include line portions and cathode portions which are wider than the line portions. Electron sources are formed on the cathode portions.
