Abstract: A method of manufacturing a display device includes providing a display layer including a light-emitting element, providing a base resin on the display layer, providing a chassis part by using a chassis providing unit including an electromagnet, providing a resin part by transforming a shape of the base resin, and separating the chassis providing unit from the display layer.

Abstract: A display device includes a first base layer defining a display area in which pixels are arranged, a second base layer at least partially under the first base layer, a first connection signal line partially on the first base layer, and a second connection signal line partially under the second base layer. The first connection signal line includes a (1-1)st part overlapping the first base layer in a plan view and a (1-2)st part that does not overlap the first base layer in the plan view. The second connection signal line includes a (2-1)st part overlapping the second base layer in the plan view and a (2-2)st part that does not overlap the second base layer in the plan view. At least a portion of the (2-2)st part overlaps the (1-2)st part in the plan view, and the (1-2)st part and the (2-2)st part are electrically connected.

Abstract: A method for manufacturing a display device includes providing a display layer including a light emitting element; providing a first coupling layer on the display layer; providing a chassis module including a chassis, a second coupling layer, and a chip-on-film; moving the chassis module; and disposing the chassis module on the first coupling layer.

Abstract: A display device has a display area with a plurality of light emitting areas and a non-light emitting area between the light emitting areas and a non-display area around a periphery of the display area. The display device includes: a base substrate having a first surface and an opposite second surface; a light emitting element in each of the light emitting areas on the first surface; a light blocking pattern in the non-light emitting area and in a light blocking area of the non-display area; a printed circuit film attached to a pad area of the non-display area on the first surface; and a light blocking layer on the light blocking pattern and the printed circuit film. The pad area is nearer to an end of the base substrate than the light blocking area is, and the light blocking layer includes a black resin and overlaps the light blocking pattern.
