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 display device includes: a first substrate, a second substrate, a light-blocking portion, a pixel, and a wiring line. The second substrate has a main face opposite a main face of the first substrate. The light-blocking portion is disposed on the main face of the first substrate, including an opening, and blocking light. The pixel is disposed on the main faces of the first substrate and the second substrate and delimited by at least a part of the opening. The wiring line is disposed on the main face of the second substrate and at least partially overlapping the opening. The wiring line has a projection protruding toward a first substrate side. The projection has a surface including a curved surface and comprises a plurality of projections disposed at intervals in locations overlapping at least the opening.
