Abstract: A nanoprojector panel formed of an array of cells, each cell including a liquid crystal layer between upper and lower transparent electrodes, a MOS control transistor being arranged above the upper electrode, each transistor being covered with at least three metallization levels. The transistor of each cell extends in a corner of the cell so that the transistors of an assembly of four adjacent cells are arranged in a central region of the assembly. The upper metallization level extends above the transistors of each the assembly of four adjacent cells. The panel includes, for each assembly of four adjacent cells, a first conductive ring surrounding the transistors, the first ring extending from the lower metallization level to the upper electrode of each cell, with an interposed insulating material.
