Abstract
In order to attain that in an LCD display arrangement (TV) the voltage across the picture element (12) is inverted during each TV field period, two diodes (9, 19) per picture element are used, which are each connected to a separate row electrode (8). Each row electrode (8) is common to two rows of picture elements (12). Thus, arbitrary LCD liquids may be used, while the number of row connections is equal to the number of rows of picture elements.
