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.

DETAILED DESCRIPTION It is an object of the present invention to provide a redundantly constructed liquid crystal display which has high aperture efficiency.
In the liquid crystal display apparatus of the present invention, in which a plurality of pixels are arranged in a matrix at the intersections of a plurality of scan lines and a plurality of data lines, and storage capacitor lines are provided to supply the pixels with storage capacitors, the improvement comprises the pixels being arranged in groups of two pixels closely adjoining each other by arranging said scan lines so that for groups of two closely adjoining pixels, one storage capacitor line is provided every two adjoining pixels between the scan lines, the storage capacitor line being disposed in the same direction as that of said scan lines (or between a plurality of the data lines in the direction of the data lines) so that two storage capacitors corresponding to two adjoining pixels for each said group of pixels are provided, and one auxiliary capacitor is provided to be shared by every two adjoining pixels.
