ABSTRACT:
Disclosed is a liquid crystal display device comprising a substrate; a plurality of pixel electrodes arranged in matrix; a plurality of data bus lines, each of the data bus lines being arranged between two adjacent pixel electrodes in row direction; a plurality of gate bus lines spaced from each other, each of the gate bus lines being arranged between two adjacent pixel electrodes in column direction and being intersected with each of the data bus line; and a plurality of thin film transistors arranged in matrix on the substrate, wherein each of the thin film transistors has a gate electrode formed on the substrate to be connected to the gate bus line, a source electrode extended from one part of the gate bus line up to a crossing portion of the data and gate bus lines to be connected to the data bus line, and a drain electrode extended from the other part of the gate electrode to the pixel electrode, and is arranged corresponding to each of the pixel electrodes. The source, electrodes is formed to prevent the data bus line from being electrically disconnected. Even if an electrical disconnection of the data bus line occurs due to a step existing in the crossing portion of the gate and data bus lines, the data bus line remains connected to the source electrode.
