Abstract: A liquid crystal display panel includes an active matrix substrate, a color filter substrate, and a liquid crystal layer. The color filter substrate includes a black matrix that include a plurality of first portions that each overlap a plurality of source bus lines of the active matrix substrate in plan view and a plurality of second portions that intersect the plurality of first portions and each overlap a plurality of gate bus lines of the active matrix substrate in plan view, and a plurality of spacers. Of the plurality of first portions, a first portion that is adjacent to at least part of the plurality of spacers has a base portion. A width of the base portion in a direction perpendicular to a direction in which the first portion extends is larger than a width of other portions.
