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 for creating a gap therebetween;

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

    each of said plural pixels including 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 said each of said plural pixels, formed in any one of said substrate structures, and projecting into said zone for separating at least part of said one of said optical elements from the remaining liquid crystal.
