The present invention relates to an apparatus for manufacturing a diamond film having a large area which is used for a field emission display (FED) and a manufacturing method thereof. The apparatus for manufacturing a diamond film having a large area according to the present invention comprises a pulse laser generating system for generating a pulse laser beam, a laser beam scanner for scanning said pulse laser beam, and a vacuum chamber which includes a target and a substrate holder, wherein said laser beam having passed said laser beam scanner is irradiated on said target, and wherein a substrate on which a diamond film is to be formed by a plume produced from said target is set up to said substrate holder. The diamond film according to the present invention has a uniform electrical and mechanical properties and can be obtained in a short time period and with a uniform width and a large area. The diamond film manufactured according to the present invention can be also used for manufacturing emitters for FED having a large area and can increase the efficiency of the target because of the possibility of using the overall area thereof.
