Patent ID: 6927832

Claim:
A liquid crystal display device, comprising: a first substrate; a second substrate opposed to the first substrate; a plurality of gate lines formed on the first substrate along a first direction; a plurality of data lines formed on the first substrate along a second direction perpendicular to the first direction to define a plurality of pixel regions at intersections of the gate and data lines; a plurality of gate pads, each of the gate pads formed at an end portion of a corresponding one of the plurality of gate lines; a plurality of data pads, each of the data pads formed at an end portion of a corresponding one of the plurality of data lines; a gate insulating film having a first density formed on an entire surface of the first substrate including the plurality of gate lines and the plurality of gate pads; a plurality of thin film transistors formed at each intersection of the gate and data lines and between respective gate lines and respective data lines; and a passivation film having a second density less than the first density formed on an entire surface of the first substrate including the plurality of thin film transistors, the plurality of data lines, and the plurality of data pads.
