Abstract
A frameless display device includes a conductive connection body formed on a substrate. A first via is formed in a protective layer and located above the conductive connection body. A second via hole is formed in the substrate and located under the conductive connection body. A circuit layout layer is connected through the first via with the conductive connection body and a flexible connection circuit connected to a drive circuit board is connected through the second via with the conductive connection body thereby achieving electrical connection between the drive circuit board and the circuit layout layer. The flexible connection circuit and the drive circuit board are both arranged at a back side of the substrate without occupying an effective display zone.
