Abstract: According to an aspect, a detection device includes: a photodiode provided on a substrate; a light source disposed so as to face the photodiode; and a liquid crystal panel disposed between the photodiode and the light source in a direction orthogonal to the substrate. The liquid crystal panel includes a plurality of pixels. In plan view, the photodiode has a size larger than a size of each of the pixels, and the photodiode is disposed in a position overlapping the pixels. The liquid crystal panel is configured to bring at least one of the pixels overlapping the photodiode into a transmitting state and bring another of the pixels into a non-transmitting state.
