Document Type and Number:
Japanese Patent JP6597035
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a photodetector structured so as to lessen a decrease in quantity of light of pixel on which light is made incident and so as to prevent multi-reflected light from being made incident on an adjacent pixel.SOLUTION: A photodetector comprises: a first pixel having a common electrode, a first active layer provided on the common electrode, a first electrode provided on the first active layer, and a first optical coupling structure provided on the first electrode; a second pixel having a second active layer provided separately from the first pixel, a second electrode provided on the second active layer, and a second optical coupling structure provided on the second electrode; and a groove provided in the common electrode, on the side where the first and second pixels are provided, but between the first and second pixels. The above problem is solved by the photodetector.SELECTED DRAWING: Figure 3
