Abstract: A display device comprises a substrate, a semiconductor layer thereon, a first insulating layer on the semiconductor layer, a first conductive layer on the first insulating layer and including a first electrode pattern, a second insulating layer on the first insulating layer and including first and second conductive patterns, a third insulating layer on the second conductive layer, and a display element layer on the third insulating layer and including a first pixel electrode connected to the first conductive pattern through a first via hole, a second pixel electrode connected to the second conductive pattern through a second via hole, and a micro light-emitting element between the pixel electrodes, the first conductive pattern contacting the semiconductor layer through a first contact hole and the first electrode pattern through a second contact hole, and the second conductive pattern overlapping the first electrode pattern to form a first capacitor therewith.

Abstract: A porous membrane structure includes a fibrous host material, which defines a plurality of inter-fiber voids, and a porous guest polymer that fills at least a subset of the plurality of inter-fiber voids of the fibrous host material. The porous guest polymer facilitates selective transport of materials across the porous membrane structure and provides selective barrier properties to the porous membrane structure. The porous membrane structure may be configured as a protective barrier material for use across a range of applications.
