A thin film transistor array panel includes: gate lines; data lines insulated from and crossing the gate lines; and shorting bars disposed outside of a display area in which the gate lines cross the data lines. The shorting bars overlap portions of the data lines disposed outside of the display area. The shorting bar includes a semiconductor material.

Thin film transistor array panel, manufacturing method thereof, and display device including the thin film transistor array panel

A thin film transistor array panel and a manufacturing method thereof according to an exemplary embodiment of the present invention form a contact hole in a second passivation layer formed of an organic insulator, protect a side of the contact hole by covering with a protection member formed of the same layer as the first field generating electrode and formed of a transparent conductive material, and etch the first passivation layer below the second passivation layer using the protection member as a mask. Therefore, it is possible to prevent the second passivation layer formed of an organic insulator from being overetched while etching the insulating layer below the second passivation layer so that the contact hole is prevented from being made excessively wide.

Thin film transistor array panel and manufacturing method thereof

A thin film transistor array panel includes: a substrate; a gate line and a common voltage line on the substrate and electrically separated from each other; a gate insulating layer on the gate line and the common voltage line; a first passivation layer on the gate insulating layer; a common electrode on the first passivation layer; a second passivation layer on the common electrode; and a pixel electrode and a connecting member on the second passivation layer and electrically separated from each other. A first contact hole and a second contact hole are defined in the first and second passivation layers. The pixel electrode and the drain electrode are connected to each other through the second contact hole. The connecting member and the common electrode are connected to each other through the first contact hole.
