Abstract

A liquid crystal display panel and a fabricating method thereof for reducing the number of data lines and the capacitance of a parasitic capacitor between pixel electrodes are disclosed. A first switching part has at least two thin film transistors for applying a first pixel signal that is supplied to a first data line to a first pixel electrode under control of the second control line and the gate line. A second switching part has at least two thin film transistors for applying a second pixel signal supplied to the second data line to the second pixel electrode under control of the first control line and the gate line. A turn-on current value of wither of the two thin film transistors, in each of the first and second switching parts, is more than that of the other thin film transistor.

Claims (7)

1. A method of fabricating a liquid crystal display panel, comprising:

providing a plurality of gate lines on a substrate;

providing a first and a second control lines in a direction parallel to the gate lines, said first and second data lines crossing the gate lines to define a first and a second pixel areas;

providing a first and a second pixel electrodes at the respective first and second pixel areas;

providing a first switching part having at least two thin film transistors for applying a first pixel signal supplied to the first data line to the first pixel electrode under control of the second control line and the gate line; and

providing a second switching part having at least two thin film transistors for applying a second pixel signal supplied to the second data line to the second pixel electrode under control of the first control line and the gate line,

wherein any one of said at least two transistors has a larger channel width than the other transistor.
