A device for forming a surface pattern of fluid includes: fluid that can be hardened under a predetermined condition; a base unit to which the fluid is applied; and a vibration unit for vibrating the applied fluid to form a waveform on a surface of the fluid. A method for forming a surface pattern of fluid includes: a fluid receiving stage for applying fluid to a base unit; a vibration stage for vibrating the fluid applied to the base unit to form a waveform on a surface of the fluid; and a hardening stage for hardening the fluid on which the waveform is formed. The disclosed device for forming a surface pattern of fluid and the forming method thereof have an advantage of easily forming various waveform patterns on the surface of the fluid by a vibration unit for vibrating the fluid with various waveforms, frequencies, and amplitudes. Also, the present invention enables the formation of waveform patterns on the surface of the fluid without mechanical contact with the surface of the fluid so there is little restriction in the waveform pattern size, and the production cost of the waveform pattern is reduced. Further, an additional precision mold for forming a fine waveform pattern on the surface of the fluid is not needed.
