Abstract
A redundantly constructed liquid crystal display which has high aperture efficiency. Pixels are arranged in a matrix at the intersections of scan and data lines and storage capacitor lines are provided to supply the pixels with storage capacitors. The pixels are arranged in groups of two pixels adjoining each other by arranging scan lines (or data lines) in groups of two pixels closely adjoining each other. One storage capacitor line is provided for every two adjoining pixels between the scan lines (or data lines) and disposed in the same direction as the scan lines (or data lines). Two storage capacitors corresponding to the two adjoining pixels are provided for each storage capacitor line and one auxiliary storage capacitor is provided to be shared by every two adjoining pixels. Alternatively, both the scan lines and the data lines may be arranged in groups of two closely adjacent lines so that a unit or group of four adjacent pixels is formed. The storage capacitor line, then has associated with it a storage capacitor for each of the four pixels and a single auxiliary storage capacitor for the four pixels.
