Abstract: A display device in one example includes a substrate having a display area allowing an image to be displayed and a non-display area located outside of the display area. The display device further includes a light emitting element disposed in the display area of the substrate, and an encapsulation layer on the light emitting element and extending into the non-display area. Further, the display device includes a first metal dam disposed in the non-display area and located further away from the display area than the encapsulation layer in the non-display area. This configuration enables a bezel area to be extremely reduced.

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.

Abstract: Embodiments of the disclosure relate to a display device. The device includes a first substrate including at least one of red, green, and blue subpixels. The device includes a light emitting element including a first electrode, a light emitting layer, and a second electrode. The device includes a first bank having an opening exposing at least a portion of the first electrode, a first lens part on the second electrode and having a first lens including a low-refractive material corresponding to the opening, a high-refractive layer on the first bank and the first lens part and including a high-refractive material, a light conversion layer on the high-refractive layer and including a quantum dot converting light of a color corresponding to each of the red, green, and blue subpixels. The device includes a color filter layer disposed on the light conversion layer, thereby blocking light propagating to adjacent pixels.
