摘要 |
<p>Provided is a liquid crystal display device in which a gate driver applies a gate-on pulse so that a second period is longer than a first period. The first period and the second period are defined as follows. Among gate-on pulses applied before the moment of polarity inversion of a data signal, the last end of the gate-on pulse nearest to the moment of the polarity inversion is earlier than the end time of the horizontal period during which the gate-on pulse is applied. The first period starts at the last end of the gate-on pulse and ends at the end time of the horizontal period during which the gate-on pulse is applied. The second period starts at the moment of the polarity inversion and ends at the moment of the application start of the gate-on pulse nearest to the moment of the polarity inversion among the gate-on pulses applied after the polarity inversion. Thus, even when a data signal waveform is not sharp upon polarity inversion, it is possible to suppress display unevenness and perform a high-quality display.</p> |
