Abstract

An OLED device includes a substrate, a semiconductor element on the substrate and including an active layer, a first gate electrode on the active layer, a second gate electrode on the first gate electrode, and source and drain electrodes, a wiring connection structure electrically connected to the semiconductor element and including an active layer pattern spaced from the active layer and corresponding to a first region, a second region, a third region between the first region and the second region, and a fourth region, a first gate electrode pattern overlapping the active layer pattern and expose active pattern layer at the first region and the second region, and a second gate electrode pattern contacting a portion of the first gate electrode pattern in the third region, and contacting the active layer pattern in the first region, and a sub-pixel structure on the semiconductor element and the wiring connection structure.
