Abstract: A method of fabricating a display device includes forming a thin-film transistor including a gate electrode, a source electrode and a drain electrode on a substrate, forming a first insulating layer and a second insulating layer on the thin-film transistor, forming a common electrode on the second insulating layer by depositing a common electrode material on the second insulating layer, plasma-treating a photoresist pattern on the common electrode material, and etching the common electrode material using the plasma-treated photoresist pattern as a mask, defining a contact hole in the second insulating layer which corresponds to the drain electrode using the plasma-treated photoresist pattern and the common electrode as a mask, forming a third insulating layer on the second insulating layer and the common electrode to expose the contact hole and the drain electrode and forming a pixel electrode connected to the drain electrode on the third insulating layer.

Abstract: A display device includes a first substrate, first signal lines, and a first signal pad array. The first signal pads each includes a first pad portion connected to a corresponding first signal line, a second pad portion having a width larger than that of the first pad portion, and a third pad portion connecting the first pad portion with the second pad portion and having a width smaller than the width of the second pad portion. The first signal pads are disposed in a shape symmetrical with respect to an imaginary line. Each first signal pad has an angle between a direction in which the third pad portion is extended and a direction in which the second pad portion is extended. The angle of a first signal pad closer to the imaginary line is smaller than the angle of another first signal pad further away from the imaginary line.
