The present invention provides an array substrate and a liquid crystal display. The liquid crystal display panel provided by the embodiment of the present application comprises an array substrate. The array substrate reduces the pretilt angle conflict between two adjacent areas by canceling the main electrode of the buffer area, or setting projection part on the array substrate after canceling the main electrode of the buffer area, adding DBS electrodes, etc. This prevents the problem of mutual obstruction of liquid crystal molecules when deflecting, thereby improving dark mass and solving the problem of uneven display.
