PROBLEM TO BE SOLVED: To provide an irregular display having a large stroke of a display member, and capable of regulating easily a deformation direction of an expansion member. SOLUTION: This irregular display 1 is provided with a housing member 2 having opening parts 200a-200f and storage parts 201a-201f, the plurality of display members 3a-3f having inner end parts 31a-31f and outer end parts 30a-30f, and the expansion member 4 having a plurality of pairs of electrodes 400a-400f, 401a-401f arranged correspondingly to the plurality of display members 3a-3f, and an expansion film 41 made of a dielectric elastomer interposed between the plurality of pairs of electrodes 400a-400f, 401a-401f, and interposed between the opening parts 200a-200f and the plurality of inner end parts 31a-31f. The expansion member 4 is deformed along a direction to guide the expansion member 4 into the storage parts 201a-201f, using an energizing force accumulated preliminarily in the expansion member 4, when driven.
