Abstract: A display device includes a backplane line disposed on a substrate, a protective layer overlapping the backplane line, a first electrode disposed on the protective layer, a light emitting element electrically connected to the first electrode, and a reflective pattern including a reflective material and disposed between the substrate and the first electrode, the reflective pattern overlaps the backplane line in a plan view.

Abstract: An embodiment vehicle lower body includes a front lower body and a rear lower body spaced apart from each other in a longitudinal direction, each including multiple pipes and having wheels and a suspension mounted thereto, a pair of lower body main members each having a pipe shape and spaced apart from each other in a lateral direction, the pair of lower body main members connecting upper end sides of the front lower body and the rear lower body and extending in the longitudinal direction to define upper side members of the front lower body and the rear lower body, and a pair of lower body floor members each having a pipe shape and spaced apart from each other in the lateral direction, the pair of lower body floor members connecting lower end sides of the front lower body and the rear lower body.

Abstract: A hard film-coated cutting tool comprises: a hard base material and a hard film formed on the hard base material, wherein: assuming that a colorimetric diffusion reflectance value is LSCER and a total reflectance value is LSCIR, the relationship of 0.65?LSCER/LSCIR?0.85 is satisfied, and when surface roughness is measured on the rake surface of the hard film within the range of 100 ?m from the edge, an arithmetic average height SaR is within the range of 0.2 ?m?SaR?0.5 ?m; and assuming that, at a flank surface of the hard film, a colorimetric diffusion reflectance value is LSCEF and a total reflectance value is LSCIF, the relationship of LSCEF/LSCIF?0.9 is satisfied, and when surface roughness is measured on the flank surface of the hard film within the range of 100 ?m from the edge, an arithmetic average height SaF is within the range of 0.15 ?m?SaF?0.4 ?m.

Abstract: In the quorum sensing antagonist blocking the communication in bacteria, the method for preventing biofilm formation using this quorum sensing antagonist and the method for reducing the bacterial contamination, the quorum sensing antagonist contains the homoserine lactone moiety and sulfanylethanoyl group, and has a similar chemical structure to that of the autoinducer which is produced by bacteria as a signal, whereby the quorum sensing antagonist can inhibit the formation of biofilm and reduce the bacterial contamination as well.
