Abstract
Electro-optical display screen with control transistors wherein a cell of liquid crystal is controlled by the transistors and the row conductors set on one side of the cell as well as by the column conductors (C1, C2) set on the other side of the cell. Each transistor (T11) has its electrode gate (cg11) connected to a row conductor (L1), its source (cs11) connected to a neighbouring row conductor (L2) and its drain (cd11) connected to an electrode of the cell (E11). In a screen of this type, there is thus no intersection between conductors on one and the same side of the screen, nor between additional control conductors, an arrangement that provides for easier access to the control conductors.
