Abstract: Provided is a method for manufacturing a field emission array with a carbon microstructure. The method includes: a photomask attachment step of attaching a photomask with a pattern groove to one surface of a transparent substrate; a photoresist attachment step of attaching a negative photoresist to one surface of the photomask; an exposure step of irradiating light toward the opposite surface of the transparent substrate from the photomask to cure a portion of the negative photoresist with the light irradiated on the negative photoresist through the pattern groove; a developing step of removing an uncured portion of the negative photoresist while leaving the cured portion of the negative photoresist as a microstructure; a pyrolysis step of heating and carbonizing the microstructure thus obtained; and a cathode attachment step of attaching a voltage-supplying cathode to the surface of the transparent substrate on which the microstructure is formed.
