Patent ID: 8817217

Claim:
A display substrate comprising: an insulating substrate; a plurality of signal lines disposed on the insulating substrate, wherein each signal line includes a pad formed on one end portion of the signal line; a first pixel electrode electrically connected to each signal line through a switching element; a second pixel electrode disposed overlapping the first pixel electrode; a plurality of connection lines, wherein each connection line makes contact with the other end portion of a corresponding signal line and extends in a same direction as the corresponding signal line to an end portion of the insulating substrate, and wherein the end portion of the insulating substrate is disposed adjacent to the other end portion of the corresponding signal line; and an insulating layer disposed between the first and second pixel electrodes and covering the connection lines, wherein the display substrate is configured to be cut along a cutting line crossing the connection lines after the display substrate has been tested, and wherein the connection lines are formed of a different layer than the signal lines.
