First Claim
Patent Images

1. An in-plane switching type liquid crystal display panel for producing images, comprising:

  • a pair of substrate structures opposed to each other and defining a gap therebetween;

    a liquid crystal filling said gap, and serving as optical elements of plural pixels where said images are produced, wherein each of said plural pixels comprises;

    a common electrode formed in one of the substrate structures of said pair, a pixel electrode formed in said one of said substrate structures in an offset manner to said common electrode, and defining a zone in said liquid crystal together with said common electrode for accommodating one of said optical elements of said plural pixels therein, and a switching transistor formed in said one of said substrate structures and having a source connected to said pixel electrode, a data line extending outside of a periphery of said zone and a gate electrode extending outside of said periphery; and

    at least one partition wall structure associated with each of said plural pixels, formed in any one of said substrate structures, so that said at least one partition wall structure separates the liquid crystal between said common electrodes and said pixel electrodes from the liquid crystal between one of said data line and said common electrode formed along said data line and the liquid crystal between said gate electrode and said common electrode.
