A liquid crystal display panel and the preparing method are to provide an active element array base plate and an opposite base plate. A shared potential input circuitry is set on the active element array base plate and a shared electrode layer is set on the opposite base plate. Many conducting projection are formed on the shared potential input circuitry or the shared electrode layer. Then to distribute a frame glue and a liquid crystal layer on the active element array base plate and an opposite base plate. The frame glue is round the liquid crystal layer and the conducting projection in the frame glue is connected to the shared potential input circuitry and the shared electrode layer, the active element array base plate has some space with the opposite base plate by the conducting projection. |
