Abstract
A display device includes a first transistor, a second transistor electrically connected thereto, n third transistors electrically connected to a gate of the first transistor and connected to each other in series, a capacitor to be charged with a voltage corresponding to a data signal, and a light emitting element, wherein the third transistors include a semiconductor area including a channel area, a source area, a drain area, and a gate overlapping the channel area, wherein the source area or the drain area that is closer to the gate of the first transistor, and that is of the third transistor closest to the gate of the first transistor, includes a first area, and a second area between the first area and the channel area, having a doping concentration that is lower than that of the first area, and having a width that is less than that of the first area.
