Abstract
A liquid crystal display in which a reference signal main line, placed so as to connect reference signal lines to each other, is separated into an input main line and an output main line in an insulating state from each other. Then, a voltage application line from a voltage-application circuit for controlling the voltage of a reference signal is connected to the input main line and a voltage feedback line therefrom is connected to the output main line. Thus, it becomes possible to accurately detect minute voltage variations within a reference signal circuit and compensate for them.
