A display device is disclosed which is capable of suppressing characteristic changes due to a long period of conduction, thereby achieving high-quality video display, and also to provide a drive method therefor. In at least one embodiment, while sequentially activating n first scanning signal line groups G1(1) to G1(n), a predetermined voltage, which is the same as a voltage for turning off a thin-film transistor included in each pixel formation portion in that the polarity thereof is negative and is at a higher level than that voltage, is applied simultaneously to n second scanning signal line groups G2(1) to G2(n). Thereafter, while sequentially activating the n second scanning signal line groups G2(1) to G2(n), the predetermined voltage is applied simultaneously to the n first scanning signal line groups G1(1) to G1(n). By repeating this, charges accumulated in the vicinity of the thin-film transistors are eliminated, thereby suppressing changes in off characteristics thereof. At least one embodiment of the present invention is suitable for matrix display devices intended for a long period of use. |
