Active matrix display screen without spurious transistor

Claim 1

Active matrix display screen comprising: (a) a first insulating and transparent wall coating with: (i) a matrix of blocks distributed in lines and columns, these blocks being of transparent conductive material and forming pixels, each block being connected to a first conductive segment, (ii) a family of conductive addressing columns placed between the columns of blocks, each column being provided with at least a second conductive segment at the level of each pixel, each second segment connected to a determined column having a part which is interposed between the first segment connected to the block and the column which follows said determined column, (iii) a family of conductive addressing lines perpendicular to the addressing columns and placed between the lines of blocks, these lines consisting of a stack of a semiconductive material, these lines covering said first segments connected to the conductive blocks and said second segments connected to the columns, a matrix of transistors thus being constituted there where the lines cover said first and second segments, each transistor of this matrix comprising a gate formed by the conductive layer of a line, a source formed by the first segment connected to the block and a drain formed by the second segment connected to a column, (b) a second insulating and transparent wall coated with a transparent conductive layer, (c) a layer of liquid crystal inserted between the first and the second wall.
