ABSTRACT:
The invention relates to a three-dimensionally controlled liquid crystal matrix display having a low number of connections and transistors to its control process. The display comprises a first insulating wall covered with electrode rows, each formed from n aligned row strips, a second insulating wall covered with electrode columns, each formed by r aligned column strips, and a liquid crystal layer inserted between the electrode columns and the electrode rows. The row strips and the column strips are respectively grouped into p first and second packets of s parallel row strips, and of t parallel column strips, with p=n.times.r, s=m.times.n/p and t=q.times.r/p. Each row strip and each column strip is associated respectively with a transistor serving to interconnect the row strips and interconnect the column strips to form s row connections, t column connections, and p packet connections.
