The first insulating layer is disposed on the substrate, the second insulating layer is disposed on the first insulating layer, and the third insulating layer is disposed on the second insulating layer. The scan lines are disposed below the third insulating layer on the substrate in the pixel area, and are disposed on the third insulating layer in the peripheral area.

Abstract: The present disclosure relates to a plurality of host materials, organic electroluminescent compounds, and organic electroluminescent devices comprising the same. By comprising specific combinations of compounds according to the present disclosure as the plurality of host materials or by comprising a compound according to the present disclosure, it is possible to provide organic electroluminescent devices having improved lifespan characteristics compared to conventional organic electroluminescent devices.

Abstract: A display device includes a substrate including a display area and a peripheral area disposed around the display area. The peripheral area includes a bending region and a contact region adjacent to the bending region. A first connection line includes a first portion disposed in the contact region, and a second portion disposed in both the bending region and the contact region, and including a first layer and a second layer. At least part of the second layer of the second portion overlaps the first layer of the second portion. In the contact region, the first layer of the second portion is electrically connected to the first portion, and the second layer of the second portion is electrically connected to the first layer of the second portion.
