ABSTRACT:
An improved active matrix type liquid crystal display panel is provided, the liquid crystal display panel being characterized in that the one picture element, formed on an active matrix substrate, is divided into a plurality of subelements and is connected to at least two scanning or signal lines through respective switching elements disposed on each display electrode or that each pair of the neighboring picture elements belonging to different rows or columns of the matrix is staggered with respect to each other and as a result the density of picture defects can significantly be reduced and the formation of echelon images can effectively be eliminated even if an oblique or curved line is reproduced.
