Abstract:
1. A liquid crystal display device comprising on an insulating substrate a plurality of source signal lines, a plurality of gate signal lines, a plurality of pixels, and a source signal line driving circuit for driving the source signal lines, wherein the source signal line driving circuit has a plurality of analog buffer circuits, wherein switching circuits are provided between the analog buffer circuits and the source signal lines, wherein a connection between one of the source signal lines and one of the analog buffer circuits is periodically switched to a connection between the one of the source signal lines and another one of the analog buffer circuit by any one of the switching circuits, wherein at least one of the analog buffer circuits is connected to at least first and second contact points of the switching circuits. wherein a set of n (n is a natural number that satisfies 2≦n) periods is repeated periodically, and wherein, in an r-th period (r is a natural number that satisfies 1≦r≦n), the switching circuit connects an m-th source signal line (m is a natural number that satisfies 1≦m) to an (m+r−1)-th analog buffer circuit.
