Abstract: An inkjet head device comprises a body comprising light emitting devices, a nozzle installed on a lower side of the body to spray the light emitting devices onto the substrate in units of droplets, and a first guide part disposed in the body to guide the light emitting devices to the nozzle in a line. Since the light emitting devices arranged in a line by the first guide part are dropped on the substrate in units of a predetermined amount of droplets, the number of light emitting devices included in each droplet may be the same or similar. Thus, since the same or similar number of light-emitting elements are disposed or aligned in each sub-pixel, the luminance in each sub-pixel obtained by the light-emitting elements can be uniform.
