In addition, if the micro-dispenser of the present invention is applied to a color filter manufacturing method, manufacturing costs can be reduced and productivity can be increased. [Embodiment] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, the embodiments of the present invention described below can be changed into various forms, and the scope of the present invention is not limited to the embodiments described below. The embodiments of the present invention are intended to fully explain the present invention to persons having ordinary skills in the related art. Fig. 1 is a schematic sectional circle of a micro-dispenser according to the present invention, and a second circle is an enlarged flat circle of a micro-nozzle of the first volume. The micro-dispenser 103 of the present invention includes a solution storage tank 13 located in a main body 11 having a predetermined space, and the solutions therein, such as R (red), G (green), and B (blue) color material solutions, are shot from the outside. Into. In other words, a solution such as a red, green, and blue color material solution is injected from the outside through a separate supply device and stored in the solution storage tank 13. Below the solution storage tank 13, there is a micro-nozzle 5 which can discharge a solution of color 4 materials, such as red, green, and blue. The micro-nozzle 15 includes a plurality of small holes 17 so that a viscous solution, such as a color material solution, will not be discharged when the surface tension is lower than a predetermined stress. The number of small holes 17 can be changed depending on the use. The micro-nozzles 15 can be made into a circle, a rectangle or a polygon. Micro-spray

According to this embodiment ', the width and height of the micro-nozzle 15 are 100 m and 80 #m, respectively, but may be changed if necessary. Above the solution storage tank 13, there is a vibration plate 19, a strain gauge 21 ', and a pressure actuator 23. Specifically, the strain gauge 21 is located between the vibration plate 19 and the pressure actuator 23. When a voltage is applied to the force actuator 23, the pressure actuator 23 generates vibration. The vibration thus generated is transmitted to the solution storage tank 13 through the strain gauge 21 and the vibration plate 19 so as to discharge a solution such as a color material solution through the micro-nozzle 15 as a stress. The vibration increases when passing through the vibration plate 19. The pressure actuator 23 controls the amount of voltage applied so that the density and frequency of vibrations are controlled. Of course, if a voltage is not applied to the pressure · actuator 23, a solution such as a color material solution in the solution storage tank 13 will not be discharged. The strain gauge 21 can accurately measure how much stress the pressure actuator 23 transmits to the solution storage tank 13. If the stress transmitted to the solution storage tank 13 is accurately measured, the amount of the solution, such as the discharged color material solution, can be accurately controlled based on this standard dish measurement.
