摘要： A display device includes a display panel having first and second regions with the second region having a higher resolution than the first region and an electronic module under the first region. The display panel includes first and second emission layers in a first sub-region of the first region with the second emission layer being spaced apart from the first emission layer. The first emission layer has a first light-emitting portion and a second light-emitting portion adjacent to the first light-emitting portion in a first direction, and the second emission layer has a third light-emitting portion and a fourth light-emitting portion adjacent to the third light-emitting portion in the first direction. The first light-emitting portion is inclined from the second light-emitting portion toward a lower surface of the display panel, and the fourth light-emitting portion is inclined from the third light-emitting portion toward an upper surface of the display panel.
