Abstract: PURPOSE: To display an image of constant quality in a liquid crystal display device independently of dispersion of the capacity characteristic of a liquid crystal display device and the signal condition for displaying image. CONSTITUTION: Signal J1, J2, J3 are input from a system 44 to a gate timing control circuit 50 of a driving circuit 42. The signal J1, J2, which are previously stored in the timing control circuit 50, include the information for selecting any one of plural data, which show each different timing for turning on and off a gate line 28 of a LCD 10, and the timing control circuit 50 selects any one of the plural data on the basis of the signal J1, J2, and generates the gate line control signal YOE on the basis of the selected data, and output this signal to a gate line driver 30. The gate line driver 30 drives the gate line 28 in a timing based on the gate line control signal YOE.

Abstract: PROBLEM TO BE SOLVED: To provide a liquid crystal display device capable of reducing flickers irrespective of any display pattern. SOLUTION: In a 1st frame, driving voltages with polarities defined according to random numbers in the unit of rows are applied, and in the following 2nd frame, the driving voltages of the inverted polarities of those in the 1st frame are applied. The polarity patterns are alternately repeated.
