Abstract: According to an aspect, a detection device includes: a photosensor including light-receiving elements; a front light including a light guide plate and a light source configured to emit light to a first side surface of the light guide plate; and an optical filter layer provided between the light-receiving elements and the front light. The optical filter layer includes light guide paths and a light-blocking portion. A first opening of each light guide path closest to the light-receiving elements is offset in a direction more away from the light source than a second opening of the light guide path farthest from the light-receiving elements. The light guide plate includes a scattering portion on the optical filter layer side. A first peak of an intensity of first light emitted from the detection surface of the light guide plate is observed to be tilted toward a side opposite to the first side surface.
