ABSTRACT:
Active matrix display screen with row and column redundancy. The display screen comprises a first and second transparent plate (10, 24) between which is inserted a liquid crystal. On a first plate (10) are deposited a matrix of elements (32) each comprising a transistor (20) and a conductive block (22), lines of addressing electrodes organized in rows (14) and in columns (12). The lines of electrodes are connected together at their ends by resistances which make it possible to avoid the effects of row or column breaks.
