Tactile display apparatus according to an embodiment may include a second electrode on the first electrode, the electroactive polymer between the pillar structures of the support, the support pole structure on the first electrode, and the electroactive polymer. Although the six pillar support structures per surface intersecting the first electrode and the second electrode are shown in the plan view it is not limited to the number of the support. In addition, the cross section of the pillar is not limited to a rectangle. If an external voltage is applied may be an electroactive polymer shrinkage. For example, when the electroactive polymer is a dielectric elastomer, in proportion to the square of the size of the external voltage it may be contracted in the thickness direction (z direction). A support pole structure can not be deformed by the shrinkage of the external voltage, and the electroactive polymer. Thus, the pillar structure are inserted into the support portion may be more protruding toward the upper surface and lower than cotton outside of the electroactive polymer. In addition, the first electrode and the second electrode can be deformed according to a protruding shape so compliant electrode. As a result, the display device can be obtained which can provide a catalyst during / texture applied external voltage.
