Detection device with coupling portion for photodiodes

A detection device comprising:

• a glass substrate;
• a first detection element comprising a first photodiode and a second detection element comprising a second photodiode, the first detection element and the second detection element being formed in a detection region on the glass substrate;
• a light-blocking layer overlapping the first photodiode and the second photodiode in the detection region and having a plurality of openings;
• and
• a plurality of lenses overlapping each of the first photodiode and the second photodiode, wherein
• each of the first photodiode and the second photodiode comprises a plurality of partial photodiodes,
• the number of the partial photodiodes of the first photodiode is equal to the number of the partial photodiodes of the second photodiode,
• the number of the openings that overlap the partial photodiodes of the first photodiode in the first detection element differs from the number of the openings that overlap the partial photodiodes of the second photodiode in the second detection element,
• each of the first photodiode and the second photodiode further includes a coupling portion coupling the partial photodiodes,
• a length of the coupling portion in a first direction perpendicular to an extending direction of the coupling portion, is less than a length of each of the partial photodiodes in the first direction, and
• none of the openings is provided in an area overlapping the coupling portion.
