Abstract
Provided is a display device possessing a first pixel, a second pixel, a partition wall, and an emission-quenching layer. The first pixel includes a first pixel electrode, a first emission layer located over the first pixel electrode and containing a first emission material, and an opposing electrode over the first emission layer. The second pixel is adjacent to the first pixel and includes a second pixel electrode, a second emission layer located over the second pixel electrode and containing a second emission material, and the opposing electrode. The emission-quenching layer is sandwiched by the partition wall and the opposing electrode and contains at least one of the first emission material and the second emission material at a concentration higher than at least one of a concentration of the first emission material in the first emission layer and a concentration of the second emission material in the second emission layer.
