Patent ID: 8363195

Claim:
A display device of an active-matrix type having a plurality of pixels arranged in rows and columns, comprising: scanning signal lines; a scanning signal line driving circuit that drives the scanning signal lines; auxiliary capacitor signal lines formed in each separate one of the rows; and an auxiliary capacitor signal line driving circuit that drives the auxiliary capacitor signal lines, the scanning signal line driving circuit supplying scanning signals, the auxiliary capacitor signal line driving circuit supplying auxiliary capacitor signals, the scanning signals and the auxiliary capacitor signals being supplied to a display region through one and the same edge of or opposite and different edges of the display region, each of the rows being provided with a plurality of said scanning signal lines for supplying those ones of the scanning signals which have different pulse widths from each other, said pixels of the same row being divided into a plurality of groups according to which of the scanning signal lines the pixels are connected to, the plurality of groups being arranged along the scanning signal lines, the pulse widths of said scanning signals that are supplied to the respective groups being set according to a position of each of the groups with respect to the auxiliary capacitor signal line driving circuit such that one of the groups which is further from a point close to one edge near the auxiliary capacitor signal line driving circuit with respect to the auxiliary capacitor signal line driving circuit is supplied with that one of the scanning signals which has a smaller pulse width.
