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.

Abstract: A display device includes a substrate, a first insulating layer, a power lines, and connection lines. The substrate includes a peripheral area adjacent to at least one side of a pixels area. The first insulating layer including one or more contact holes. The power line is in the peripheral area and provides a driving voltage to pixels. The power line includes a first metal layer on the substrate and a second metal layer connected to the first metal layer through the contact hole. The connection lines extend to the peripheral area from the pixels and overlap part of the power line. The power line includes a first area in which the first and second metal layers are electrically connected through the contact hole. The connection line does not overlap the first area of the power line.
