Abstract
A thin imaging device including a light source is provided. The imaging device includes a light-emitting device which emits infrared light. Infrared light emitted by the light-emitting device and reflected by a subject is received by a photoelectric conversion device included in a pixel circuit. Since an EL element is used as the light-emitting device, a thin imaging device with a light source can be formed. A pixel circuit utilizing an oxide semiconductor transistor having a property of low off-state current is used, whereby image capturing by a global shutter method is possible and a distortion-free image can be obtained even when the subject is moving.
