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: Disclosed are a catalyst for producing ethylene, and carbon monoxide from ethane and carbon dioxide via chemical looping process, a method for producing the same, and a chemical looping process using the same. The catalyst includes a complex metal oxide containing iron (Fe), cerium (Ce), and titanium (Ti). The catalyst has improved ethylene selectivity, carbon monoxide conversion, and stability.
