Abstract
In the present invention, occurrence of abnormality such as display misalignment at the time of image update is prevented even when pause drive is performed in a display device where data signal lines are driven by a plurality of driver ICs. In a liquid crystal display device which includes a master IC (L) and a slave IC (R) as driver ICs and performs pause drive, upon detection of refresh start timing by a REF (Half) of the master IC (L), the master IC (L) transmits a refresh control signal RfC to the slave IC (R), and upon receipt of a refresh detection signal RfD indicating refresh start timing detected by a REF (Half) of the slave IC (R), the master IC (L) transmits the refresh control signal RfC to the slave IC (R) as well as starts refreshing on the left active area based on data in a 1/2 RAM (L). Upon receipt of the refresh control signal RfC, the slave IC (R) starts refreshing on a right active area based on data in a 1/2 RAM (R).
