Abstract:
An electrophoretic display device including a first substrate, a second substrate, an electrophoretic material interposed between the first substrate and the second substrate, the electrophoretic material including a positively charged particle and a negatively charged particle, a common electrode provided on the second substrate, a pixel provided at an intersection of a signal line and a scan line, the pixel provided in a plural number and arranged in matrix on the first substrate. The electrophoretic display device further including a pixel electrode provided in the pixel, a capacitor line provided in the pixel, a storage capacitor provided in the pixel, and a second electrode of the storage capacitor being coupled to a storage capacitor line and a thin film transistor (TFT) provided in the pixel, a source electrode of the TFT being coupled to a first electrode of the storage capacitor and the pixel electrode, a drain electrode of the TFT being coupled to the signal line, and a gate electrode of the TFT being coupled to the scan line. A capacitor line low select signal VSL or a capacitor line non-select signal VSC having a higher electric potential than an electric potential of the capacitor line low select signal VSL is supplied to the storage capacitor line.
