Abstract: Provided are a scanning driving circuit and a liquid crystal display device. The scanning driving circuit comprises multiple cascaded scanning driving units (1). Each scanning driving unit (1) comprises an input module (100) for outputting a low-level signal and a plurality of driving circuits (200). Each driving circuit (200) corresponding drives one scanning line. Each driving circuit (200) comprises: a control module (210), for outputting a control signal according to the received low-level signal; an output module (220), and a pull-down module (230), for being connected or cut off according to the received control signal; scanning lines (G(N−1), G(N), G(N+1)), for outputting a high-level or low-level scanning driving signal to pixel units. When the output module (220) is cut off, the pull-down module (230) is connected, and the scanning lines (G(N−1), G(N), G(N+1)) output the low-level scan driving signals to the pixel units; and when the output module (220) is connected, the pull-down module (230) is cut off, and the scanning lines (G(N−1), G(N), G (N+1)) output high-level scanning driving signals to the pixel units. Accordingly, a circuit of the liquid crystal display device is simplified, and the space is saved, thereby facilitating the narrow-frame design of the liquid crystal display device.

Abstract: Disclosed is a liquid crystal display panel. An array substrate of the liquid crystal display panel comprises at least two pixel units. One pixel unit comprises: a scan line extending along a first direction; a data line extending along a second direction, different from the first direction; a pixel electrode; and a thin film transistor which is disposed in a functional connection between the data line and the pixel electrode. At least a part of the two adjacent pixel units are arranged mirror-symmetrically to each other. A new wire design is provided, so that a spacer can be arranged to avoid a PLN via hole, which effectively prevents the spacer of the panel from sliding into the PLN via hole while a liquid crystal cell is assembled or during a bending test procedure.
