Abstract: A display panel includes a base layer, and a light emitting element layer having a plurality of light emitting regions spaced apart from each other and a non-light emitting region. The light emitting element layer includes a first electrode, a pixel-defining film, a hole transport region, a light emitting layer to correspond to the plurality of light emitting regions, an electron transport region, and a second electrode. The electron transport region integrally overlaps the plurality of light emitting regions and the non-light emitting region, and the hole transport region does not overlap at least a portion of the non-light emitting region.

Abstract: A thin film transistor according to an exemplary embodiment of the present invention includes an oxide semiconductor. A source electrode and a drain electrode face each other. The source electrode and the drain electrode are positioned at two opposite sides, respectively, of the oxide semiconductor. A low conductive region is positioned between the source electrode or the drain electrode and the oxide semiconductor. An insulating layer is positioned on the oxide semiconductor and the low conductive region. A gate electrode is positioned on the insulating layer. The insulating layer covers the oxide semiconductor and the low conductive region. A carrier concentration of the low conductive region is lower than a carrier concentration of the source electrode or the drain electrode.
