Abstract
Embodiments relate to an array substrate for a flat display device and a method of fabricating the same for reducing an over etch at a portion of the substrate where a data line is applied in a diagonal shape during the etching of the data line. As a result, disconnection of the data line may be reduced, which in turn reduces the failure rate of the flat display devices and enhances process yield.
Claims9
An array substrate for a flat display device, the array substrate comprising:
- a substrate comprising a display region and a non-display region disposed at an edge of the display region;
- a plurality of gate lines disposed in the display region and a plurality of data lines vertically crossed with the plurality of gate lines;
- and
- a plurality of gate link lines configured to apply gate signals to the plurality of gate lines and a plurality of data link lines configured to apply data signals to the plurality of data lines,
- wherein at least the outermost data link line of the plurality of data link lines comprises an end portion, the end portion connected to a corresponding data line of the plurality of data lines, and wherein the outermost data link line is the data link line closest to the outermost edge of the non-display region;
- wherein the end portion comprises a horizontal portion extending from the corresponding data line, a vertical portion perpendicular to the corresponding data line, and a diagonal portion having a diagonal shape connected between the horizontal portion and the vertical portion,
- wherein a line width of the diagonal portion is greater than a line width of the horizontal portion or vertical portion.
