    摘要: An image on a liquid crystal is displayed with a constant picture quality, independent of the capacity characteristic variations of the display and the conditions of signals for displaying an image. A gate-timing control circuit 50 of a drive circuit receives input signals J1, J2, and J3 from a system 44. The signals J1 and J2 are prestored in the timing-gate control circuit 50 and contain information for selecting any of a plurality of data, each representing different timing at which a gate line 28 of an LCD 10 is turned on and off. The timing control circuit 50 selects any of the plurality of data according to the signals J1 and J2, generates a gate line control signal YOE based upon the selected data, and outputs it to a gate line driver 30. The gate line driver 30 drives the gate line 28 at timing corresponding to the gate line control signal YOE.
