Abstract
A display device includes: a substrate; pixels, the pixels each including at least one transistor and a light emitting device connected to the transistor; data lines and scan lines connected to the pixels; and a power line supplying power to the light emitting device. The transistor includes an active pattern on the substrate, source and drain electrodes each connected to the active pattern, a gate electrode on the active pattern, an interlayer insulating layer covering the gate electrode, the interlayer insulating layer including a first interlayer insulating layer, a second interlayer insulating layer, and a third interlayer insulating layer, which are sequentially stacked, and a protective layer provided on the interlayer insulating layer. The third interlayer insulating layer includes a concave part in a region in which the light emitting device and the second conductive layer overlap with each other, and the second conductive layer is in the concave part.
