An array substrate and a total reflection liquid crystal display panel are provided. By disposing an uneven surface which is at least partially uneven on a side of a planarization layer away from a substrate in the total reflection liquid crystal display panel, a reflection electrode can be disposed along the uneven surface of the planarization layer in an uneven shape, thereby changing an reflective direction of a light in the panel. Therefore, the light that cannot be reflected at a critical angle of total reflection originally is allowed to be reflected out of the panel, thereby increasing reflectivity of the total reflection liquid crystal display panel.
