<p>The present invention relates to a flat lamp device for TFT-LCD using a carbon nano tube capable of eliminating an after-image, wherein the flat lamp device has a high uniformity and a low power consumption. For this purpose, the present invention provides a flat lamp device for TFT-LCD using a carbon nano tube, including: a cathode electrode; carbon nano tubes installed on the cathode electrode; a grid electrode installed over the carbon nano tubes to induce electron emission from the carbon nano tubes; an anode electrode installed over the grid electrode and accelerating electrons emitted from the carbon nano tubes; a phosphor layer formed on a lower surface of the anode electrode and colliding with the accelerated electrons to emit the light; and a controller for applying a voltage pulse to the cathode electrode so that the phosphor layer can emit light.</p> |
