    Abstract: A light-emitting element is provided to improve light emission efficiency of a light-emitting element. The light-emitting element includes: a first electrode; a second electrode; a quantum dot layer provided between the first electrode and the second electrode, in which quantum dots are layered; and a hole-transport layer provided between the quantum dot layer and the first electrode, wherein the hole-transport layer includes a plurality of layers each containing a different material, the plurality of layers of the hole-transport layer each have an ionization potential increasing from the first electrode toward the quantum dot layer, and, among the plurality of layers of the hole-transport layer, a layer in contact with the quantum dot layer is higher in ionization potential than the quantum dot layer.

    IPC: G01N27/22

    Abstract: A detection device includes a plurality of detection units formed on a semiconductor circuit, a correction capacitive element that indicates a correction capacitance value for correcting detected capacitance values detected by the detection units, a difference acquisition circuit that acquires a difference value between each of the detected capacitance values and the correction capacitance value, and a conversion circuit that converts the difference value into a digital signal. The correction capacitive element, the difference acquisition circuit, and the conversion circuit are formed on the semiconductor circuit.
