US 6,583,777 B2 · Active matrix type liquid crystal display device, and substrate for the same

Abstract

An active matrix type liquid crystal display device has a plurality of data lines and a plurality of gate lines formed on a substrate in matrix fashion, TFTs and pixel electrodes being provided at both sides of the data lines so as to correspond with each of the plurality of gate lines, and the plurality of gate lines are positioned such that the pixel electrodes at both sides of the data lines are controlled by signals from one of the two gate lines sandwiching the pixel electrodes, i.e., either the first or second gate line. Also, the gate electrodes comprising TFTs are comprised of gate lines themselves, so that the drain electrodes electrically connected to the pixel electrodes traverse the gate electrodes. Thus, the pixels can be driven with fewer data lines than with known arrangements.

Dependent claims

An active matrix type liquid crystal display device substrate, comprising:

a plurality of data lines and a plurality of gate lines provided on a substrate in a matrix form, the data lines being without overlap;
and
thin-film transistors and pixel electrodes connecting to said thin-film transistors provided on one side of each of said data lines, corresponding with each of said plurality of gate lines, adjacent gate lines having one of the thin-film transistors and pixel electrodes disposed therebetween;
wherein drain electrodes of said thin-film transistors connected with said pixel electrodes are provided on the same side of the gate lines as gate electrodes extending from said gate lines, with at least two of said data lines being electrically connected;
and
wherein thin-film transistors connected to each of said connected data lines are each controlled by a different ate line of the plurality of gate lines.
