Original Abstract Submitted
a display device includes a pixel circuit disposed on a base layer and including a transistor including a source electrode, a drain electrode, a gate electrode, and a semiconductor layer, and a light emitting element electrically connected to the pixel circuit. the semiconductor layer includes a low concentration area, a high concentration area, and a slope concentration area between the low concentration area and the high concentration area, which are divided based on a concentration of a carrier and are spaced apart from each other in a length direction of the base layer. the low concentration area and a portion of the slope concentration area form a channel area, and form a source area and a drain area including the high concentration area and at least another portion of the slope concentration area. in the slope concentration area, the semiconductor layer satisfies an equation.
