摘要:
An electron emission device includes a pair of anode and cathode substrates facing each other, and cathode electrodes, an insulating layer, and gate electrodes sequentially deposited on the cathode substrate. Gate holes are formed within the respective pixels by partially removing the gate electrodes and the insulating layer. Each pixel is divided into a central pixel region and a peripheral pixel region. Electron emission regions are placed on the cathode electrodes inside the gate holes to emit electrons. Anode electrodes and a phosphor screen are formed on the anode substrate. A uniform electric field is applied to the electron emission regions arranged at the central pixel region, and a non-uniform electric field is applied to the electron emission regions arranged at the peripheral pixel region excluding the central pixel region.
