Abstract
In one embodiment of the present application, a display is disclosed in which any defective pixel is rendered less noticeable even if a full-screen white display or suchlike is effected. In a normally-white liquid crystal display device, which transitions after power activation from non-display state through display starting state, where a full-screen blank white display is effected, to normal display state, an auxiliary electrode driver portion controls an auxiliary capacitance line voltage Vto be applied to auxiliary capacitance lines in accordance with the state of the liquid crystal display device in the following manner. Specifically, during the display starting state, the voltage difference between the auxiliary capacitance line voltage Vand a counter voltage Vis set at 0, such that any defective pixel is displayed in white, whereas during the normal display state, a predetermined voltage difference ΔVis caused between the auxiliary capacitance line voltage Vand the counter voltage V, such that any defective pixel is displayed in black. The present invention is suitable for active-matrix liquid crystal display devices.
