PURPOSE: A method for manufacturing a field emission display device is provided to equalize the heights of focus electrodes of the field emission display device so as to increase manufacturing efficiency. CONSTITUTION: A method for manufacturing a field emission display device includes following steps. At the first step, a field emission tip(26) and a gate electrode(30) are formed on the surface of a lower substrate(22). At the second step, an insulation layer(28) is formed on the surface of the lower substrate. At the third step, a seed layer(36) is formed on the surface of the insulation layer. At the forth step, a mold is formed by using a photoresist on the seed layer. At the fifth step, the photoresist, the seed layer, and the insulation layer are removed sequentially. The insulation layer is coated on the surface of the substrate with a predetermined thickness by using a spin coating method.
