A method of forming a spacer for a liquid crystal display (LCD) device is disclosed. To form the spacer, an ink jet injection nozzle is aligned over a substrate on which unit pixels are arranged in a matrix. After aligning the nozzle, first dispensing spacers are dispensed from the injection nozzle with a certain gap so that at least one unit pixels is interposed between the spacers. Subsequently, the nozzle is moved and second dispensing spacers are dispensed by the nozzle at each of the unit pixels formed between the first spacers. This is repeated until the spacer is formed at all unit pixels. The spacer contains a ball spacer and a volatile liquid, which is vaporized during dispensing. The ink jet injection method prevents adjacent spacers from interfering with each other during formation.
