Abstract: A display device includes a conductive pattern on a substrate, a via layer on the conductive pattern with a via hole exposing the conductive pattern, a first electrode and a second electrode on the via layer and spaced apart from each other, a first insulating layer on the first electrode and the second electrode, a bank layer on the first insulating layer defining an emission area and a subarea, a light-emitting element on the first insulating layer, and a first connection electrode and a second connection electrode on the first insulating layer and the light-emitting element. The first connection electrode electrically contacts an end of the light-emitting element, and the second connection electrode electrically contacts another end of the light-emitting element. The bank layer includes a bank extension portion extended to the subarea and the bank extension portion overlaps at least a portion of the via hole.

Abstract: A display device includes: a substrate; a first bank including a first sub-bank and a second sub-bank spaced apart from each other on the substrate; a first electrode on the first sub-bank; a second electrode on the second sub-bank and spaced apart from the first electrode; and a light-emitting element between the first sub-bank and the second sub-bank. Each of the first and second sub-banks has a first area having a concave curved shape in a cross section and being adjacent to the light-emitting element. The first electrode has a first section extending beyond the first sub-bank toward the light-emitting element, the second electrode has a first section extending beyond the second sub-bank toward the light-emitting element, and a width of the first section of the first electrode is different from a width of the first section of the second electrode.

Abstract: A liquid crystal display device according to the present invention includes: a first substrate; a first color filter and a second color filter provided on the first substrate and including an overlapping portion where at least parts of the first and second color filters overlap each other; and a light blocking member formed between the first substrate and the overlapping portion, wherein the light blocking member includes a recessed portion corresponding to the overlapping portion of the first color filter and the second color filter. According to the present invention, the recessed portion is formed in the light blocking member provided in the overlapping portion of two or more color filters to reduce a step difference caused by the overlapping portion of the color filters, thereby preventing an alignment defect.
