<p>Disclosed is a dot display device in which multiple plate-shaped actuators are arranged in a plane, which makes it possible to decrease the thickness of the device and facilitates the wiring of each actuator. A lower wiring board (40) is located on the lower side of multiple actuators (32a, 32b, etc.) and an upper wiring board (50) is located on the upper side of said actuators. The multiple actuators (32a, 32b, etc.), the lower wiring board (40), and the upper wiring board (50) are interposed between a lower case (10) and an upper case (20). The base end parts of the individual actuators (32a, 32b, etc.) are held by pressing sections on the lower case (10) and the upper case (20). Each of the multiple protrusions (31) are pushed up by the free ends of the actuators (32a, 32b, etc.), which causes dots to be displayed in the dot display sections (D1, D2, etc.).</p> |
