ABSTRACT:
Voltage lines (6) for the reference voltage running parallel to the row electrodes (7) in a display device of the reset type provide the possibility of separately testing and repairing the picture electrodes (4) and the associated switching units (5, 11) for each pixel before connection to the reference voltage. Moreover, the device thus obtained can be driven with single-row inversion, while a larger aperture is possible and the occurrence of artefacts can be reduced.
