Abstract
A display device is made up of (i) a source driver made up of source driver ICs each driving an identical number of data signal lines, the source driver ICs being grouped into at least a first individually-driven circuit group and a second individually-driven circuit group, and (ii) a control circuit that outputs a first start pulse and a first latch pulse for controlling the first individually-driven circuit group and a second start pulse and a second latch pulse for the second individually-driven circuit group. With this, it is possible to provide the display device that can reproduce images without adopting complicated circuitry and elongating one horizontal period, when the source driver has dummy signal lines.
