ABSTRACT:
A liquid crystal display screen including a substrate with conductive addressing columns and conductive blocks, each including a block lengthening piece, a layer of semiconductive material followed by a layer of nonconductive material formed on the addressing columns and conductive blocks, and conductive addressing lines formed on the nonconductive material and each overlapping a block lengthening piece. The block lengthening pieces, the conductive addressing columns, and the conductive addressing lines form addressing transistors. Also, capacitive lines are formed on the nonconductive material and overlap the conductive blocks such that the conductive blocks, the semiconductive material, the nonconductive material, and the capacitive lines form storage capacitors.
