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 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.

Abstract: A wiring board includes first lines and second lines extending along a first direction, a first electrode connected to the second lines, a third line extending along a second direction crossing the first direction, and a signal supply connected to the first lines and not connected to the second lines and the third line. At least two first lines that are arranged at an interval in the second direction and overlap at least two second lines, respectively, via an insulating film, and are defined as second line overlapping first lines. The signal supply is configured to supply a first signal to one of the second line overlapping first lines and supply a second signal having an opposite polarity from a polarity of the first signal to another one of the second line overlapping first lines. The third line is connected to the at least two second lines.

Abstract: A display device includes: a plurality of first color filters not intersecting a non-linear portion with at least a part of an outer shape of a display region being non-linear, a plurality of second color filters at least part of which intersects the non-linear portion, a first region with the plurality of first color filters disposed, a second region with the plurality of second color filters disposed, a first light blocking portion partitioning the plurality of first color filters, a second light blocking portion partitioning the plurality of second color filters, and a spacer. An overlapping area of the second light blocking portion with respect to the plurality of second color filters is larger than that of the first light blocking portion with respect to the plurality of first color filters. A distribution density of the spacer in the second region is lower than that in the first region.
