Abstract: Thermoelectric conversion cells of a thermoelectric conversion element include a thermoelectric conversion layer formed on a main surface of a substrate, an insulating layer covering the thermoelectric conversion layer, a first electrode including a first layer and a second layer, and a second electrode. The first layer connects to the main surface of the thermoelectric conversion layer via a first contact hole, and the second layer covers the first layer. The second electrode connects to the main surface of the thermoelectric conversion layer via a second contact hole. The second layer and the second electrode, and the first layer are formed from materials having different work functions.

Abstract: A microdevice includes: a microchannel to which a measurement target solution containing a measurement target substance is introduced; an antibody being fixed to at least one sidewall surface of the microchannel and specifically binding to the measurement target substance; a fluorescence-labeled derivative being specifically bound to the antibody and being acquired by fluorescence-labeling the measurement target substance; and a light blocker blocking excitation light exciting fluorescent light radiated by the fluorescence-labeled derivative. The measurement target substance and the fluorescence-labeled derivative specifically bind to the antibody in a competitive manner, and the antibody is fixed to the sidewall surface of the microchannel in a state of specifically binding to the fluorescence-labeled derivative. The light blocker blocks the excitation light entering the fluorescence-labeled derivative specifically binding to the antibody.

Abstract: An imaging device includes a substrate, photodiode semiconductor layers on the substrate, an upper electrode and a lower electrode sandwiching the photodiode semiconductor layers, and a non-light-transmissive line included in a layer upper than the upper electrode, defining the substrate as the lowermost layer. The photodiode semiconductor layers include a first semiconductor layer, and a second semiconductor layer located between the first semiconductor layer and the lower electrode. The photodiode semiconductor layers have a groove in which the first semiconductor layer is removed in a region covered with the non-light-transmissive line in a planar view. A region overlapping the groove in the planar view does not include the upper electrode. The region overlapping the groove in the planar view includes a part of the second semiconductor layer and a part of the lower electrode.

Abstract: An image sensor includes pixels arrayed on a substrate and a data line that transmits a signal read from each of the pixels. The pixel includes a photodetector and an N-type switch thin film transistor between the photodetector and the data line. The switch thin film transistor includes an oxide semiconductor part, a gate electrode, a drain electrode towards the data line, and a source electrode towards the photodetector. An overlap region where the gate electrode and the drain electrode overlap in a plan view is smaller than an overlap region where the gate electrode and the source electrode overlap in a plan view.

Abstract: A display device includes a substrate and a plurality of first light-emitting elements having a microcavity structure on the substrate. Each of the plurality of first light-emitting elements includes a first light-emitting film and a first upper electrode and a first lower electrode sandwiching the first light-emitting film. The peak wavelength of an emission spectrum of the first light-emitting film is in a wavelength range where the luminosity curve slopes negatively. Within a wavelength range where the peak wavelength of a multiple interference spectrum caused by the microcavity structure varies when the viewing angle varies from 0° to 60°, the luminosity curve slopes negatively, and the emission spectrum slopes positively.
