A display device includes a substrate, a display structure, and a conductive line. The substrate includes a display region having a plurality of pixel regions and a peripheral region surrounding the display region. Each of the pixel regions has sub-pixel regions and a transparent region. The display structure is disposed in each of the pixel regions of the display region. The conductive line is disposed in the peripheral region, and is electrically connected to the display structure. The conductive line has at least one opening.
