    • A rotating terminal (16) has a circumferential outer peripheral surface (21a, 24a) having its center disposed at an axis (13, 21b) of rotation of the rotating terminal, and has electrically conductive areas and non-electrically conductive areas alternately arranged on the outer peripheral surface in the circumferential direction. At least one pair of fixed terminals (17, 18) are fixed and disposed outwardly of a path of rotation of the outer peripheral surface of the rotating terminal. In accordance with a rotating position of the rotating terminal, the pair of fixed terminals can be switched between an electrically-conducting condition, in which the pair of fixed terminals are electrically connected together through the rotating terminal, and an interrupting condition in which the pair of fixed terminals are not electrically connected together through the rotating terminal.

    • A liquid crystal display device includes a liquid crystal display panel in which pixels are arranged in rows and columns. Each of the pixels includes a pixel electrode, and a thin-film transistor having a gate electrode and a drain electrode. Gate signal lines arranged in the rows are connected to the gate electrodes of the thin-film transistors. Drain signal lines arranged in the columns are connected to the drain electrodes of the thin-film transistors. The liquid crystal display device further includes a gate drive circuit for driving the gate signal lines, and a drain drive circuit for driving the drain signal lines. The drain drive circuit receives a plurality of grey-scale reference voltages from an external circuit, interpolates a plurality of intermediate voltages between each pair of adjacent ones of the grey-scale reference voltages, selects voltages from the grey-scale reference voltages and the intermediate voltages, and applies the selected voltages to the drain signal lines. V0 is a grey-scale reference voltage corresponding to a minimum grey-scale level, Vm is a grey-scale reference voltage corresponding to a maximum grey-scale level, and Vi is a grey-scale reference voltage that is nearest to a voltage level (Vm+V0)/2. A number of intermediate voltages interpolated between V(i−1) and Vi is different from both a number of intermediate voltages interpolated between V0 and V1, and a number of intermediate voltages interpolated between V(m−1) and Vm.
