Document Type and Number:
WIPO Patent Application WO/2020/036014
Kind Code:
A1
Abstract:
A light detection device according to one embodiment of the present disclosure is provided with: a light blocking film that comprises a plurality of light transmitting regions and a plurality of light blocking regions, which are alternately arranged in a first direction and in a second direction that intersects with the first direction; a light detector that has an imaging surface and comprises a plurality of first light detection cells and a plurality of second light detection cells, which are arranged on the imaging surface; and a light coupling layer which is positioned between the light blocking film and the light detector, and which comprises a grating that causes some of light to propagate in the first direction and in the second direction when light is incident on the plurality of light transmitting regions.
