Abstract: A rotor of a rotating electrical machine includes a rotor core, a plurality of magnetic pole portions arranged along a circumferential direction, and a plurality of arc magnets constituting the magnetic pole portions. Each magnetic pole portion includes a magnet portion of at least two layers along a radial direction. In front view, the rotor core includes an outer diameter side magnet insertion hole, an inner diameter side magnet insertion hole, and a refrigerant flow path hole provided between an outer diameter side magnet portion and an inner diameter side magnet portion to overlap a d-axis. A minimum width of a magnetic path formed between the outer diameter side magnet insertion hole and the refrigerant flow path hole is equal to or larger than a minimum width of a magnetic path formed between the outer diameter side magnet insertion hole and the inner diameter side magnet insertion hole.

Abstract: A liquid crystal display device is provided that has favorable display characteristics in a display mode using a vertical electric field and a horizontal electric field. This liquid crystal display device includes a first substrate and a second substrate arranged facing each other, and a liquid crystal layer sandwiched between the first substrate and the second substrate. The liquid crystal layer has liquid crystal molecules having a negative dielectric anisotropy, and the first substrate has a plate-shaped first common electrode and a pixel electrode formed in a separate layer from the first common electrode with an insulating film therebetween. The pixel electrode has a comb-shaped structure, and the second substrate has a second common electrode with a liquid crystal orientation structure that is linear in a plan view.
