1. A detection device comprising:
an array substrate including
a plurality of scan lines each extending in a first direction, the scan lines arranged in a second direction,
a plurality of signal lines each extending in the second direction, the signal lines arranged in the first direction,
a first detection element disposed in a first region surrounded by two scan lines adjacent to each other in the second direction and two signal lines adjacent to each other in the first direction, and
a second detection element disposed in a second region adjacent to the first detection element in the first direction, the second detection element being surrounded by two scan lines adjacent to each other in the second direction and two signal lines adjacent to each other in the first direction; and
an optical filter including
a first light-transmitting resin layer having a first surface facing the first detection element and the second detection element, and a second surface opposite to the first surface,
a single first light-blocking layer provided between the array substrate and the first surface of the first light-transmitting resin layer, and
a plurality of lenses provided to a side of the second surface of the first light-transmitting resin layer,
wherein
the single first light-blocking layer includes:
a plurality of openings arranged in a first arrangement pattern in the first region; and
a plurality of openings arranged in a second arrangement pattern in the second region,
the first arrangement pattern is different from the second arrangement pattern in planar view,
the lenses in the first region are arranged a third arrangement pattern and overlap the openings arranged in the first arrangement pattern,
the lenses in the second region are arranged a fourth arrangement pattern and overlap the openings arranged in the second arrangement pattern, and
the third arrangement pattern is different from the fourth arrangement pattern, in planar view.
