Abstract: An electroluminescent display device includes: a substrate, a first electrode on the substrate, a connection pattern on the substrate, the connection pattern including a same material as the first electrode, a bank covering edges of the first electrode and the connection pattern, a light-emitting layer on the first electrode, a second electrode on the light-emitting layer, the bank, and the connection pattern, and an auxiliary pattern between the connection pattern and the second electrode, the auxiliary pattern including one or more of: a metal oxide, conductive nanoparticles, and a work function-modifying polymer.

Abstract: The present disclosure relates to a cosmetic composition containing an extract of Cyperus rotundus extracted using warm microbubbles. The extract inhibits nitric oxide (NO) production and exhibits excellent anti-inflammatory efficacy by inhibiting the expression of interleukin 6 (IL-6), cyclooxygenase-2 (COX-2), interleukin-1? (IL-1?), and tumor necrosis factor-? (TNF-?), which are inflammatory expression factors. In addition, the extract enhances the expression of aquaporin-3 (AQP-3), hyaluronan synthase 2 (HAS-2), claudin-1 (CLDN-1), cadherin 1 (CDH1), filaggrin (FLG), and involucrin (IVL), which are genes related to the skin barrier and moisturizing. Thus, when using the extract for cosmetic products, excellent effects can be exhibited in skin soothing, moisturizing, enhancement of the skin barrier, relief of irritation such as erythema, relief of pruritus, and the like, so the extract can be usefully applied to multi-care products that improve skin conditions.
