<P>PROBLEM TO BE SOLVED: To provide a display capable of reducing a load of pump and curbing electric power consumption. <P>SOLUTION: A film is provided on a predetermined surface of a main body, and includes a first area deformable by pressure of liquid led to the inside and a second area attached to the main body and arranged on the outside of the first area. An injection passage is equipped with a first port at a part covered by the film on the surface of the main body where the film is provided, and supplies liquid to the first port. A discharge passage is equipped with a second port at a part covered by the film on the surface of the main body where the film is provided, and discharges the liquid from the second port. A first pump applies a pressure to the inside of the injection passage so as to supply liquid to the first port. A second pump applies a pressure to the inside of the discharge passage so as to discharge the liquid from the second port. A first valve switches between the conducting and blocking states of the first port, and a second valve switches between the conducting and blocking states of the second port. <P>COPYRIGHT: (C)2012,JPO&INPIT |
