A forming method of spacers in a flat panel display is provided. The method includes the steps of preparing a plurality of spacers (50) in a predetermined shape, preparing a substrate (10) on which the spacers are to be attached in the flat panel display, applying a photosensitive adhesive material (40) on an upper surface of the substrate to a predetermined thickness, aligning the spacers on the substrate to attach the spacers by using the photosensitive adhesive material, radiating light onto the substrate from above the substrate to expose portions of the photosensitive adhesive material without the spacers, and removing the exposed portions of the photosensitive adhesive material. Therefore, the spacers are fixed on the substrate by the photosensitive adhesive material located under the spacers. According to the provided method of forming spacers, the spacers are fixed on the substrate by a mounting process using a jig, a temporary exposing process, and a developing process. In this case, the spacers are simultaneously placed on the substrate by the jig so that the spacers can be precisely aligned. The characteristic of the provided method of forming spacers is very effective in mass production of flat panel displays.
