Patent ID: 8089204

Claim:
A display panel comprising: a rear substrate on which a cathode is disposed, the cathode having an electron-emitting area in which a plurality of electron-emitting elements is located; a front substrate on which an anode is disposed, the anode having a light-emitting area in which a plurality of light-emitting elements is located; a plurality of plate shape spacers disposed between the rear substrate and the front substrate, each of the plurality of plate shape spacers comprising an electric resistor element and a potential regulating element connected to the electric resistor element; a frame disposed between the rear substrate and the front substrate, and surrounding the plurality of plate shape spacers; and a thermal conducting member having a higher thermal conductance than that of the front and rear substrates, wherein an inner space surrounded by the rear substrate, the front substrate and the frame is maintained at a pressure lower than atmospheric pressure, the electron-emitting area and the light-emitting area are disposed in opposition to each other in the inner space, and each of the plurality of plate shape spacers extends from a first region between the electron-emitting area and the light-emitting area in the inner space to a second region outside of the first region in the inner space, and the electric resistor element is disposed in the second region and is connected to the cathode and the anode, and the potential regulating element is disposed in the first region along a longitudinal direction of the plate shape spacer and is spaced from the cathode and the anode, a part of a surface of the front substrate opposite to a surface thereof facing the rear substrate is connected to a part of a surface of the rear substrate opposite to a surface thereof facing the front substrate, through the thermal conducting member and the electric resistor element is disposed between the part of the surface of the rear substrate and the part of the surface of the front substrate and outside of the first region between the electron-emitting area and the light-emitting area.
