Patent ID: 7411294

Claim:
A display device comprising a display panel and a circuit substrate connected to the display panel, wherein the display panel includes at least one array substrate, the circuit substrate is separately formed and positioned different from said array substrate and comprises an insulating substrate, a conductive layer, an insulating layer to cover a part of the conductive layer, the conductive layer of the circuit substrate includes a wiring pattern, wiring terminals, and a misalignment detection pattern for detecting the misalignment between the conductive layer and the insulating layer, the wiring terminals are exposed from the insulating layer and are applied with a plating layer to a surface exposed from the insulating layer, and the misalignment between the conductive layer and the insulating layer is smaller than a predetermined misalignment tolerance, and the misalignment detection pattern comprises a pattern covered by the insulating layer in a manner to prevent adherence of a plating material to the conductive layer.
