Abstract: The embodiment of the present disclosure is directed to a display panel. The display panel includes a first substrate, a second substrate, and a liquid crystal layer. The first substrate includes a common electrode layer and a pixel electrode layer. The second substrate comprises a control electrode layer. The liquid crystal layer is between the first substrate and the second substrate. The display panel includes a display mode and a touch mode working alternately. The display mode includes an anti-peeping mode and a sharing mode. When the display panel works in the anti-peeping mode, the control electrode layer receives a first display signal. When the display panel works in the sharing mode, the control electrode layer receives a second display signal. When the display panel works in the touch mode, the control electrode layer or the common electrode layer receives a touch driving signal.

Abstract: The present invention provides a manufacturing method of a liquid crystal display (LCD) panel and the LCD panel. A thin film transistor (TFT) substrate and a color filter (CF) substrate are first bonded, a liquid crystal material is enclosed between the TFT and CF substrates to obtain a liquid crystal cell, which is then irradiated with ultraviolet light to obtain a functional liquid crystal layer, and finally a black matrix is formed on a side of the CF substrate away from the TFT substrate. By changing the structure of the existing LCD panel, the present invention prevents the shading of the black matrix that affects functional liquid crystal layer production. It is advantageous for a polymer liquid crystal technology, a self-aligned liquid crystal technology, and the like to realize a technique of forming a specific functional layer by irradiating the liquid crystal cell with ultraviolet light.
