Abstract: A storage unit stores a cumulative light emitting frequency or a cumulative light emitting time of a light emitting element. In a case where the cumulative light emitting frequency is greater than a predetermined light emitting frequency or the cumulative light emitting time is longer than a predetermined light emitting time, a control unit causes the light emitting element to emit light toward a living body by increasing the light emitting frequency or the light emitting time at which the light emitting element emits the light in order to acquire a light receiving result once, compared to a setting light emitting frequency or a setting light emitting time. A light receiving unit acquires information of the living body, based on a light receiving result obtained by receiving the light which is emitted toward the living body and transmitted through the living body.

Abstract: A biological information acquisition device selects a light emitting unit located above a blood vessel as a measurement light emitting unit, and selects a light receiving unit spaced apart from the measurement light emitting unit by a predetermined distance and located above the blood vessel as a measurement light receiving unit and causes the measurement light receiving unit to acquire a first light receiving result. The device selects a light emitting unit which is not located above the blood vessel as a reference light emitting unit, and selects a light receiving unit spaced apart from the reference light emitting unit by the predetermined distance and not located above the blood vessel as a reference light receiving unit and causes the reference light receiving unit to acquire a second light receiving result.

Abstract: A light-emitting device includes a light-emitting element disposed in a display region and including a first electrode, a second electrode, and a light-emitting functional layer. The light-emitting device includes a wiring formed in a periphery of the display region and that is electrically connected to the second electrode, and a filter layer having a first color filter that overlaps the light-emitting element and a first layer that overlaps the peripheral wiring. The first color filter and the first layer are formed from a first colored layer that transmits light having a first wavelength.

Abstract: A technique restrains degradation of a light emitting element. A biological information acquisition device acquires light receiving result by causing a light receiving unit to receive light emitted by a light emitting unit serving as a measurement-purpose light emitting unit, and acquires biological information by using the light receiving result. The light is emitted from the light emitting unit so as to acquire the light receiving result for one time, while a plurality of light emitting patterns are switched between a light emitting element which emits the light and a light emitting element which does not emit the light in a plurality of the light emitting elements.

Abstract: A detection device includes a light source which emits light, a lens, a light transmissive protecting plate, a length between the light source and the light transmissive protecting plate being larger than a length between the lens and the light transmissive protecting plate, and a light receiving element; which receives the light. An angle formed by an optical axis of the lens and the light transmissive protecting plate is smaller than an angle formed by an optical axis of the light source and the transmissive protecting plate.

Abstract: An electro-optical device includes one or more control lines that include a scanning line, a data line and a pixel circuit. The pixel circuit has a drive transistor, a write-in transistor with a gate which is electrically connected to the scanning line, a light-emitting element that emits light at a brightness that depends on the size of a current that is supplied through the drive transistor, and a control line which overlaps the gate of the drive transistor when viewed from a direction that is perpendicular to a surface of a substrate on which the pixel circuit is formed is included in the one or more control lines.
