Abstract

A display device includes a substrate including a first pixel region, a second pixel region having an area smaller than that of the first pixel region, and a peripheral region surrounding the first pixel region and the second pixel region, a second pixel provided in the second pixel region, a second line connected to the second pixel, an extension line extended to the peripheral region, a dummy part located in the peripheral region to overlap with the extension line, a power line connected to the first and second pixel regions, and a connection line located in the peripheral region to be connected to the dummy part, the connection line being electrically connected to a portion of the second pixel region, wherein the second pixel region includes a first sub-pixel region connected to the connection line and a second sub-pixel region except the first sub-pixel region.
