    摘要: The present invention realizes proper driving circuits in a driving-circuit integral type liquid crystal display device which has an increased screen size. The liquid crystal display device includes a liquid crystal display panel and a driving circuit which supplies video signals to video signal lines formed on the liquid crystal display panel. The driving circuit is comprised of a first driving circuit which is formed in a step similar to a step for forming pixels provided to the liquid crystal display panel and a second driving circuit which is connected to the liquid crystal display panel after formation of the liquid crystal display panel. The first driving circuit is constituted of a switching circuit which is capable of distributing an output of the second driving circuit to a plurality of video signal lines.
