Abstract
The spatial light modulator device (SLM) for providing a spatial light pattern which is alterable in response to an electric signal comprises a first modulator element (ME) and a second modulator element (ME). The first light beam (LB) processed by the first modulator element (ME) and the second light beam (LB) processed by the second modulator element (ME) can be superimposed for forming the spatial light pattern. In this way a defect in the first modulator element (ME) can be compensated a corresponding pixel of the second modulator element (ME). The spatial light pattern provided by the first modulator element (ME) and the second modulator element (ME) are complementary and combine to the desired spatial light pattern. The spatial light modulator device (SLM) may be used in a lithography apparatus (LA) or a display device (DD).
