A display device is provided. The display device includes a first substrate, a first charge trap layer disposed on the first substrate and including silicon nitride, a semiconductor layer disposed on the first charge trap layer and including a first active layer of a first transistor and a second active layer of a second transistor, and an organic light emitting element electrically connected to the first transistor, wherein a ratio of a content of a Si element to a content of an N element in the first charge trap layer is in a range of 1.6 to 2.5.

Display device

A display device includes a base substrate including a first substrate and a second substrate sequentially laminated, a lower semiconductor layer disposed on at least one of the first substrate and the second substrate, a buffer layer disposed on the base substrate, an active semiconductor layer disposed on the buffer layer and including a first active layer of a first transistor and a second active layer of a second transistor, a first insulating layer disposed on the active semiconductor layer, and a first conductive layer disposed on the first insulating layer and including a first gate electrode of the first transistor and a second gate electrode of the second transistor, wherein the lower semiconductor layer overlaps the first active layer, and does not overlap the second active layer.

A display device includes: a (k&#x2212;1)-th scan line and a k-th scan line which are parallel to each other; a j-th data line which crosses the (k&#x2212;1)-th scan line and the k-th scan line; and a subpixel connected to the (k&#x2212;1)-th scan line, the k-th scan line, and the j-th data line, wherein the subpixel includes: a driving transistor configured to control a driving current flowing from a first electrode thereof to a second electrode thereof according to a data voltage applied to a first gate electrode thereof, the driving transistor having a second gate electrode connected to the (k&#x2212;1)-th scan line; and a light emitting element configured to emit light according to the driving current.

An organic light-emitting display device comprising first through third pixels emitting light of first through third colors, respectively and a fourth pixel comprising first through third subpixels which emit light of the first through third colors, respectively, is disclosed.
