Abstract
A display device has a first color display panel having multi-color pixels formed of two groups of electrodes corresponding to signal electrodes and scanning electrodes. A second display panel has single-color pixels formed of two groups of electrodes corresponding to signal electrodes and scanning electrodes. The number of the signal electrodes of the second display panel are fewer in number than the signal electrodes of the first color display panel. A driver integrated circuit outputs driving signals shared commonly by and supplied to the signal and scanning electrodes of the first and second display panels. The driving signals output from the driver integrated circuit are supplied to the signal electrodes of the second display panel in only one color from among the colors of the multi-color pixels of the first display panel.
