<p>A light emitting device and a liquid crystal display device using the same are provided to improve a dynamic contrast of the LCD(Liquid Crystal Display) by independently controlling respective areas on a screen. A light emitting device includes a vacuum container, an electron emission unit(14), and a light emitting unit. The vacuum container includes first and second substrates(10,12) and a sealing member. The electron emission unit includes plural electron emitters, which are formed on the first substrate. Electron emission amounts of the electron emitters are controlled independently from one another. The light emitting unit is formed on the second substrate. The electron emitter(20) includes first electrodes, second electrodes, and first electron emitter portions. The first electrodes are formed along a cross direction of the first substrate. The second electrodes are arranged to be parallel to the first electrodes. The first electron portions are electrically connected to the first electrodes.</p> |
