A vehicle alarm device () having a novel structure is provided. The vehicle alarm device () includes a sound-source detection device (), and the sound-source detection device () includes a plurality of microphones () and a delay circuit (). As a transistor included in a signal retention circuit () inside the delay circuit (), a transistor including an oxide semiconductor (OS transistor) is used. By the sound-source detection device (), an extraneous sound is obtained and the sound-source position of the extraneous sound is identified. In the case where it is judged from the relative velocity or the like between the sound source whose position has been identified and the vehicle that the sound source and the vehicle are likely to collide, an acoustic signal for calling attention of the vehicle occupant is output.

Vehicle alarm device

An imaging device capable of executing image processing is provided. A structure is employed in which a photoelectric conversion element, a first transistor, a second transistor, and an inverter circuit are included; one electrode of the photoelectric conversion element is electrically connected to one of a source and a drain of the first transistor; the other of the source and the drain of the first transistor is electrically connected to one of a source and a drain of the second transistor; the one of the source and the drain of the second transistor is electrically connected to an input terminal of the inverter circuit; and data obtained by photoelectric conversion is binarized and output.

Imaging device and electronic device

To provide a display device with a manufacturing yield and/or a display device with suppressed mixture of colors between adjacent pixels. The display device includes a first pixel electrode, a second pixel electrode, a first insulating layer, a second insulating layer, and an adhesive layer. The first insulating layer includes a first opening. The second insulating layer includes a second opening. The first opening and the second opening are provided between the first pixel electrode and the second pixel electrode. In a top view, a periphery of the second opening is positioned on an inner side than a periphery of the first opening. The adhesive layer has a region overlapping with the second insulating layer below the second insulating layer.
