Abstract: A liquid crystal display includes a liquid crystal panel having a color filter including a red filter, a transparent filter, and a blue filter, and a backlight panel at a rear of the liquid crystal panel. The backlight panel includes electron emission regions and a phosphor layer that emits light when excited by electrons emitted from the electron emission regions. The phosphor layer includes a first phosphor layer having a red phosphor and a blue phosphor, and a second phosphor layer having a green phosphor. The backlight panel is configured to emit light from the first phosphor layer and the second phosphor layer sequentially.

Abstract: The present invention provides a composition for forming an electron emission source comprising a carbon-based material and a vehicle comprising a resin component and a solvent component. The resin component is a material that has less than 0.5 wt % of carbon deposits after undergoing a heat treatment at 450° C. under nitrogen atmosphere. The present invention also provides a method of preparing an electron emission source using the composition for forming an electron emission source, and an electron emission source that is prepared using the electron emission source. The electron emission source prepared using the composition has a small amount of the carbon deposits which improves its electric current density and lengthens its lifespan.

Abstract: An electron emission source contains a carbonaceous material and is protected by a protecting layer formed on side surfaces of the electron emission source. As a result, damages on the electron emission source by an external environment is minimized, a much clearer screen is attained, and the electron emission source exhibits high stability. An electron emission device including the electron emission source is more reliable and has a long lifetime.
