Next, the liquid crystal layer is deposited on the glass substrate on which the gel pattern is formed. Finally, the upper and lower glass substrates are combined to form a liquid crystal panel. The dispenser forms a gel pattern on the glass substrate to change the relative distance between the glass substrate and the coating head. That is, during the formation of the gel pattern on the glass substrate, the platform on which the glass material is placed is moved in one direction, and the support frame provided with the coating head is moved in a direction perpendicular to the moving direction of the platform. However, static electricity is generated when the glass substrate is placed on or removed from the platform in the dispenser, thereby causing defects in the display panel. That is, when the substrate is placed on or removed from the platform, friction between the surface of the platform and the substrate creates static electricity between the substrate and the platform. • SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to avoid static generation between a substrate and a platform during placement of the substrate on the platform and removal from the platform. According to an aspect of the invention, the present invention provides a dispenser comprising a platform having air holes, whereby the glass substrate is attracted and fixed to the platform, and the ionizer is disposed on the flat σ The lower surface of the glass substrate ejects ions to avoid static electricity, and the colloid is applied to the glass substrate.
