Abstract

A display device may reduce or minimize a size of a light emission area that becomes a dark spot due to particles. The display device includes a substrate provided with a display area for displaying an image by subpixels, first electrodes provided in each of the subpixels over the substrate, driving transistors provided between the substrate and the first electrodes and coupled to each of the first electrodes, a light emitting layer provided over the first electrodes, and a second electrode provided over the light emitting layer. Each of the first electrodes includes divided electrodes spaced apart from each other, a transistor contact portion coupled with the driving transistor through a contact hole, and connection electrodes coupling each of the plurality of divided electrodes with the transistor contact portion.
