Provided are a composite for paste including carbon nanotubes (CNTs), an electron emitting device using the same, and a manufacturing method thereof. The provided composite for paste includes 5 to 40 parts by weight of CNTs, 5 to 50 parts by weight of alkali metal silicate, and 1 to 20 parts by weight of a binder. The provided electron emitting device includes electron emitting tips, which are located on cathode electrodes in wells and formed of the composite for paste including 5 to 40 parts by weight of CNTs, 5 to 50 parts by weight of alkali metal silicate, and 1 to 20 parts by weight of a binder. The electron emitting device has excellent stability and durability and uniformly emits electrons from a large area, thereby improving the overall performance of an apparatus using the electron emitting device.
