The present invention relates to a tactile display actuator, a plurality of grooves are formed in the frame arrangement according to the invention; It is applied to the external touch, so as to cover the groove a flexible substrate that is coupled to the frame; An insulating member interposed between the bottom surface and spaced space of the flexible printed wiring board that is installed in the groove; And, is provided spaced apart from each other in the horizontal direction in the insulating member mutually isolated, and, the electrode of the first electrode pattern and a second electrode pattern pattern section for switching in accordance with the input signal; wherein the applied power to each of the electrode patterns when the surface of the flexible substrate in a position corresponding to the electrode pattern by the electrode pattern and the reverse, and the charge is induced attraction polarity occurs, the flexible substrate is the human being pulled inwardly of the spaced space of the power source by switching characterized in that the vibration to the outer and inner direction of the spacing area. In this way, of the vibration part of the actuator on both sides are formed by exposed to the air and to reduce the failure in frequent use, is formed portion and spaced to be powered from the portion is applied to the touch from the outside frequent touch in capacitance is not cumulative do not touch the display actuator is provided that can significantly reduce the malfunction.
