Electron emission device, backlight unit (BLU) including the electron emission device, flat display apparatus including the BLU, and method of driving the electron emission device

摘要

An electron emission device (101) effectively blocks an electric field generated by an anode (80), consistently and stably emits electrons at a low gate voltage, and provides a high luminous uniformity and luminous efficiency. In addition, a flat display apparatus using the electron emission device (101) as a backlight unit (BLU) and a method of driving the light emission device are provided. The electron emission device (101) includes: a base substrate (110); a first electrode (120) including a first main electrode portion (121) arranged on a surface of the base substrate (110) and extending in a predetermined direction and a first auxiliary electrode (122,123) extending from the first main electrode portion; a second electrode (130) including a second main electrode portion (131) arranged on the surface of the base substrate (110) and separated from the first electrode (120) and extending in a predetermined direction and a second auxiliary electrode (132,133) extending from the second main electrode portion (131); and an electron emission source (150) arranged on at least one of the first and second electrodes.
