Thin film transistor array substrate and fabricating method thereof
View Patent ↗A thin film transistor array substrate structure includes a plurality of data lines; a plurality of gate lines intersecting the data lines to define pixel areas, the gate line being adjacent to at least two pixel areas; a plurality of common lines disposed between the at least two pixel areas; a plurality of thin film transistors formed at each intersection between the gate lines and the data lines; a plurality of common electrodes provided substantially parallel to the common lines; and a plurality of pixel electrodes connected to the thin film transistors.
1. A method of fabricating a thin film transistor array substrate structure, comprising:
forming a gate line, a gate electrode connected to the gate line, a common line on a substrate, the common line disposed between at least two gate lines, wherein the at least two gate lines and the data line define a pixel area;
forming a gate insulating film on the substrate;
forming a semiconductor layer on the gate insulating film;
forming a data line, a source electrode and a drain electrode on the semiconductor;
forming a protective film on the substrate; and
forming a pixel electrode on the protective film, wherein the gate lines are disposed adjacently to each of at least two pixel areas, and wherein each respective one of odd-numbered gate lines are adjacent to a respective one of pre-stage even-numbered gate lines.
2. The method as claimed in claim 1 , wherein the pixel electrode includes first and second vertical portions disposed parallel to the data line and a finger portion between the first and second vertical portions.
3. The method as claimed in claim 2 , wherein the common electrode includes first and second vertical portions extended vertically from the common line and a finger portion between the first and second vertical portions.
4. The method as claimed in claim 3 , wherein the finger portion of the pixel electrode and the horizontal portion of the common electrode have a comb shape having a bent portion.
5. The method as claimed in claim 1 , wherein the common lines are formed between the odd-numbered gate lines and the even-numbered gate lines in the pixel areas.
