Abstract
A liquid crystal display panel includes features to prevent damage to the liquid crystal alignment layer when a color filter substrate and a thin-film transistor array substrate are moved relative to each other. The liquid crystal display panel may include a column spacer on the color filter substrate under the black matrix and a bump pattern on the array substrate where the column spacer and the bump pattern are in contact with each other. The array substrate may otherwise include a planarization layer with a step portion and a protective layer on the planarization layer where the protective layer is in contact with the column spacer.
