Display device

Abstract

Embodiments of the disclosure relate to a display device. Specifically, there may be provided a display device capable of mitigating leakage of light reflected at an auxiliary layer by reducing the cell gap between the light emitting element and the auxiliary layer by including a substrate including a light emitting element, a bank layer disposed on the substrate and defining an opening overlapping the light emitting element, a trench having a lower surface disposed to have a predetermined depth from an upper surface of the bank layer and a sidewall portion connecting the lower surface and the upper surface, a black matrix protruding beyond the upper surface of the bank layer and seated in the trench, a light conversion layer including quantum dots and disposed on the light emitting element, and an auxiliary layer disposed on the light conversion layer and including a reflective material.

Dependencies are inferred from the claim text.
