  • Patent number: 11756976
    Abstract: A photoelectric conversion apparatus that includes a pixel region having photoelectric conversion elements includes a semiconductor layer having first and second surfaces, and the photoelectric conversion elements are disposed between the first and second surfaces. With a virtual plane extending along the second surface between the first and second surfaces being a third plane, the pixel region includes an element isolating portion constituted by an insulator disposed closer to the first surface than the third plane, and first and second isolating portions constituted by grooves provided in the semiconductor layer to pass through the third plane. The first isolating portion overlaps the element isolating portion in a normal direction to the third plane. An end of the second isolating portion on a side on the first surface is closer to the second surface than an end of the first isolating portion on a side on the first surface is.

  • Publication number: 20220085135
    Abstract: An organic light-emitting device includes a display region, a non-display region disposed around the display region, a first organic light-emitting element disposed on a substrate and included in the display region, and a second organic light-emitting element disposed on the substrate and included in the non-display region. The first organic light-emitting element and the second organic light-emitting element each include, in an order from a side of the substrate, a first electrode, an organic layer including a light emitting layer, and a second electrode. The light emitting layer is common to and extends across the first organic light-emitting element and the second organic light-emitting element. A light-emitting threshold voltage for the second organic light-emitting element is higher than a light-emitting threshold voltage for the first organic light-emitting element.
