A driving method and a driving apparatus for a liquid crystal display device is provided. The semiconductor component further includes a pn-junction between a first semiconductor region of a first conductivity type and a second semiconductor region of a second conductivity type, the pn-junction extending in a lateral direction of the semiconductor body in the inner region. A lock mechanism 156 is released, and after the upper assembly 126 is independently raised and removed by a lift mechanism 164, maintenance of the upper assembly 126 andor the lower assembly 128 is carried out. The application of an external magnetic field alters the conductivity of the magnetic material.
