ABSTRACT:
An active matrix display device comprises an array of picture elements, e.g. liquid crystal picture elements, first and second sets of address conductors (16, 18) extending in row and column directions respectively and connected with the picture elements, and a set of connection conductor lines (30′) extending in the same direction as one set of address conductors (18), each of which is connected to a respective one of the other set of conductors (16), and via which address signals are supplied to that other set. To avoid unwanted display artefacts, each connection conductor line (30′) extends from one side of the array and terminates adjacent its connection point (32) to its associated address conductor (16) and a respective complementary conductor line (30″) is provided which extends from close to the connection point (32) to the opposite side of the array, the complementary conductor line being electrically separate from the connection line (30′) and coupled to reference signal supply (40).
