<p>PURPOSE:To easily perform performance test on a liquid crystal display panel in a state where a picture which is very similar to an actual picture is obtained by changing the driving period of the same timing signal after plural timing signal lines are connected with each other. CONSTITUTION:Blocks I, II,...N divided along a timing signal line 3 are provided for the purpose of performing inspections after influences of a resistance 7 between an auxiliary capacitor and GND and the electric current flowing through the resistance 7 are separated from each other. Driving periods of simultaneously inputted timing signals are changed in accordance with the influences of the resistance 7 between the auxiliary capacitor and ground, and the electric current flowing through the resistance 7. Therefore, the difference in voltage drops of effective video signals given to liquid crystal can be reduced. As a result, the performance of the liquid crystal can be inspected in a state where a picture which is similar to an actual picture is obtained.</p> |
