ABSTRACT:
An electron emission display that can mitigate or prevent problems of an arc discharge and a wire disconnection due to increases in resistance at portions where a sealing member contacts electrodes includes: an electron emission device on which upper surfaces of electrodes are exposed, a front panel that is disposed in front of the electron emission device, the front panel being of a phosphor material, and a sealing member that seals a space formed by the electron emission device and the front panel by being disposed on the edges of the space in contact with the electrodes. The electrodes are formed on an entire surface of the electron emission device with a narrow width at an end portion of the electron emission device where the electrodes are connected to an external power source, and the sealing member contacts the electrodes closer to the space than end portions of the electrodes where the width of the electrodes is narrowed.
