摘要： 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.

摘要： In the driving circuit for a display apparatus according to the present invention, a charging circuit applies a voltage equal to or higher than the highest positive gradation voltage to each data line for a predetermined period of time before the start of a period for applying a positive gradation voltage. After that, a positive gradation voltage in accordance with data is applied to each data line. Then, a period for the applying a negative gradation voltage is started, when a negative gradation voltage in accordance with data is applied to each data line. Accordingly, after being charged with a voltage applied by the charging circuit at the beginning of each cycle of the AC driving, each data line is applied with an equal or lower gradation voltage. Alternatively, a discharging circuit first applies a voltage equal to or lower than the lowest negative gradation voltage to each data line for a predetermined period of time before the start of a period for applying a negative gradation voltage. After that, a negative gradation voltage in accordance with data is applied to each data line. Then, a period for applying a positive gradation voltage is started, when a positive gradation voltage in accordance with data is applied to each data line. Accordingly, after being discharged with a voltage applied by the discharging circuit at the beginning of each cycle of the AC driving, each data line is applied with an equal or higher gradation voltage.
