In-plane-switching liquid crystal display for large pixel type
View Patent ↗The invention relates to an in-plane-switching liquid crystal display for large pixel type scarcely producing defects and easily repairing defects. The in-plane-switching liquid crystal display 10 of the invention comprises a plurality of pads 34 , and each pad connects to a pixel electrode 42 . Besides, each pixel electrode 42 is surrounded by the common electrode 48 . When the pixels enlarge, the defects scarcely occur. Even if the defect occurs, the defect can be easily repaired.
1. An in-plane-switching liquid crystal display, comprising:
a transparent insulating substrate;
a plurality of gate lines formed on said transparent insulating substrate and being parallel to each other;
a plurality of storage capacity lines formed between the gate lines;
an insulating layer formed on said transparent insulating substrate and covering said gate lines and said storage capacity lines;
a transistor formed on said insulating layer and having a drain electrode, a source electrode, and a gate electrode being part of a corresponding gate line;
a signal line being perpendicular to said gate lines with said insulating layer therebetween, and connected to said drain electrode;
a pixel line formed on the insulating layer in a same direction as said gate lines and connected to said source electrode;
a plurality of pads corresponding to said storage capacity line with said insulating layer therebetween;
a resin layer formed on said insulating layer and covering said transistor, said signal line, said pixel line and said pads;
a plurality of first through holes formed in said resin layer that is formed on said pads;
a plurality of second through holes formed in said resin layer that is formed on said pixel line, wherein the number of said second through holes is equal to the number of said first through holes; and
a plurality of pixel electrodes extending from said second through holes over the surface of said resin layer to said first through holes so as to connect the pixel line and the pads.
2. The display according to claim 1 , further comprising:
a first common electrode formed on said resin layer above said gate lines and said signal line; and
a second common electrode formed on said resin layer and connected to said first common electrode, said first common electrode and said second common electrode surrounding said pixel electrode.
