Abstract
An active liquid crystal matrix display panel has a plurality of display-driving circuit elements arranged in a matrix on one of the cell substrates, the circuit elements being interconnected by bus-bars. The circuit elements are produced by a group exposure method. The bus-bars are formed wider at the group exposure boundaries so as to ensure continuity of the bus-bars.
