Abstract: A display device including a lower substrate having a display region including a plurality of pixel regions, and a peripheral region surrounding the display region; a plurality of pixel structures in the plurality of pixel regions on the lower substrate; an upper substrate on the plurality of pixel structures; a seal between the lower substrate and the upper substrate in the peripheral region; and a power supply voltage wiring between the seal and the lower substrate in the peripheral region, wherein the power supply voltage wiring partially overlaps the seal, and the power supply voltage wiring includes a plurality of first openings in a portion thereof that protrudes inwardly from the seal in a first direction extending from the peripheral region into the display region.

Abstract: A display apparatus includes a substrate that includes a display area and a peripheral area around the display area; an encapsulation substrate on the substrate; a sealing portion disposed in the peripheral area between the substrate and the encapsulation substrate, wherein the sealing portion surrounds the display area; and a pattern portion on the encapsulation substrate that overlaps the sealing portion while extending parallel to the sealing portion, where the pattern portion includes a plurality of block patterns that are spaced apart from one another and a plurality of opening regions that alternate with the plurality of block patterns, and a first block pattern of the plurality of block patterns that has a largest width is located at a center of the pattern portion.
