<p>A light emitting device, a method for manufacturing an electron emission unit for the light emitting device, and a liquid crystal display device using the light emitting device as a backlight unit are provided to improve brightness of a light emitting surface by applying a voltage higher than 10 kV on an anode electrode. First and second substrates(12,14) are opposed to each other and form a vacuum container. First electrodes(22) are formed along a cross direction on the first substrate. Second electrodes(28) are formed to cross the first electrodes with an insulation layer between the first and second electrodes. Hetero metal layers are laminated on the second electrode. An electron emitter(30) is electrically connected to one of the first and second substrates. A resistor layer(26) is formed on an overall upper surface of the insulation layer and has a resistivity gradation along a thickness direction of the first substrate. A fluorescent layer(34) is formed on one surface of the second substrate. An anode electrode(36) is formed on one surface of the fluorescent layer.</p> |
