Abstract: The present invention relates to an electron emission device, and more particularly, to an electron emission device comprising a grid electrode having a thermal expansion coefficient ranging from about 80 to about 120% of the thermal expansion coefficient of the first or second substrate of the electron emission device. The grid electrode is fixed in position by minimizing misalignment caused by a difference in thermal expansion coefficients between the grid electrode and the first and second substrates of the electron emission device. The grid electrode also minimizes generation of arc discharge. However, even when arc discharge is generated, the grid electrode prevents damage to the cathode electrodes and gate electrodes from that arc discharge. According to the present invention, an electron emission device with increased brightness and resolution is easily realized by applying increased voltage to the anode electrode.

Abstract translation: 本发明涉及一种电子发射器件，更具体地说，涉及一种电子发射器件，它包括一个栅极，该栅电极的热膨胀系数约为电子的第一或第二衬底的热膨胀系数的大约80至大约120％ 排放装置。 通过最小化栅电极与电子发射器件的第一和第二衬底之间的热膨胀系数的差异引起的不对准，将栅电极固定在适当的位置。 栅格电极还可以最大限度地减少电弧放电的产生。 然而，即使产生电弧放电，栅格电极也可防止阴极电极和栅电极对电弧放电的损害。 根据本发明，通过向阳极施加增加的电压，容易实现具有增加的亮度和分辨率的电子发射装置。
