An upper electrode substrate that is provided on a display surface side; and a reflecting sheet (back surface sheet) that is provided on a back surface side of the upper electrode substrate such that an upper space (display space) is formed between the upper electrode substrate and the reflecting sheet, and such that a through hole (liquid storage space) whose one end side is connected with the upper space is formed; are provided. Moreover, an upper electrode (first electrode) is provided on an upper side and a lower side of the upper space, a lower electrode (second electrode) is provided so as to surround the through hole, and the upper electrode and the lower electrode are connected to a switch (driver) and an alternating-current power supply (driver). An upper electrode substrate 12 that is provided on a display surface side; and a reflecting sheet (back surface sheet) 10 that is provided on a back surface side of the upper electrode substrate 12 such that an upper space (display space) 11 is formed between the upper electrode substrate 12 and the reflecting sheet 10, and such that a through hole (liquid storage space) 15 whose one end side is connected with the upper space 11 is formed; are provided. Moreover, an upper electrode (first electrode) 30 is provided on an upper side and a lower side of the upper space 11, a lower electrode (second electrode) 32 is provided so as to surround the through hole 15, and the upper electrode 30 and the lower electrode 32 are connected to a switch (driver) 35 and an alternating-current power supply (driver) 36.
