Abstract

A display device capable of improving image quality by minimizing or reducing a vertical current leakage, an electronic device including the display device, and a method for fabricating a display device are provided. The display device includes: a substrate (SSUB); a reflective electrode (RL) on the substrate; an optical auxiliary layer (OAL) on the reflective electrode; a first electrode (AND) on the optical auxiliary layer; a light emitting stack (IL) on the first electrode; a second electrode on the light emitting stack; a pixel defining layer (PDL) arranged between adjacent first electrodes; a planarization layer (PNS) on the pixel defining layer; and an auxiliary trench (AXT) defined by a top surface of the pixel defining layer, a side surface of the first electrode, and a side surface of the planarization layer.
