ABSTRACT:
A second device (24) is mounted on a first device (22) formed of a liquid crystal (27) display cell (26) at the front of which is arranged a first linear polarizer (40), of a liquid crystal (29) optical valve (28) at the back of which is arranged a second polarizer (44) and means (23) for controlling the valve (28) and the cell (26) from a switched state to a non switched state. When the cell (26) is switched to display a data item, by associating a first light or dark device (22) with a second absorbent or reflective polarizer (44), an inversion of the contrast in said data is obtained by switching the valve (28).
