Abstract: A liquid crystal display panel includes an active matrix substrate including a gate layer including gate lines, a source layer including source lines, and an alignment film covering the gate layer and the source layer, a color filter substrate, placed opposite the active matrix substrate, that includes a black matrix including, in planar view, first portions separately overlapping each of the source lines and second portions crossing the first portions and separately overlapping each of the gate lines and spacers disposed in cross regions in which the first portions and the second portions cross each other, and a liquid crystal layer disposed between the active matrix substrate and the color filter substrate. The active matrix substrate further includes bank portions provided in positions surrounding the spacers within regions overlapping the cross regions in planar view.

Abstract: A liquid crystal display device includes source wiring lines, and first electrode and second electrode configured to generate a fringe electrical field. The first electrode includes slits. Each slit forms an acute angle with pixel short-hand direction defined in row direction smaller than an acute angle formed by each slit and pixel longitudinal direction defined in column direction. The slits include first slits each extending an acute angle in a clockwise direction with respect to the pixel short-hand direction, and second slits each extending an acute angle in a counterclockwise direction with respect to the pixel short-hand direction. The first electrode includes first region in which the first slits are formed, and second region in which the second slits are formed. In a plan view, each source wiring line is bent at a position corresponding to a boundary between the first region and the second region.
