    摘要: A display device includes a display panel, and the circuit substrate is separately formed and positioned different from the array substrate of the display panel and connected to the display panel. The circuit substrate includes an insulating substrate, a conductive layer, an insulating layer to cover a part of the conductive layer, a plating layer applied to a portion of the conductive layer which is exposed from the insulating layer due to misalignment between the conductive layer and the insulating layer, and a misalignment detection pattern for detecting the misalignment between the conductive layer and the insulating layer. The misalignment detection pattern has a pattern covered by the insulating layer in a manner to prevent adherence of a plating material to the conductive layer, if the misalignment between the conductive layer and the insulating layer is smaller than a predetermined misalignment tolerance.
