Abstract
An active matrix array of display elements and nine drain line drivers are formed on a substrate. The drain line drivers are separated into three groups each containing three drain line drivers. Individual drain lines are connected to different drain line drivers in a layout order. Clock signals, which are obtained by frequency-dividing a D-clock signal to one ninth and which have phases shifted from one another by 120 degrees, are supplied via three clock signal lines that commonly connect associated drain line drivers in the individual groups in parallel. All the drain line drivers in each group are connected in parallel by a data signal line. Thinned video data signals obtained by separating input video data by three are supplied via the three data signal lines group by group.
