PROBLEM TO BE SOLVED: To provide a light detector not lowering response speed, when performing light detection by using a photoelectric conversion function of a light detection part.SOLUTION: In a light detector constituted so that a light transmission type light detection part 2 is placed on the front side of eyes of a subject 4, for detecting as the whole light detection part 2 correspondingly to light intensity of incident light to be detected by each light detection element 2a of the light detection part 2, a two-dimensional signal reading circuit (19, 16a) transmissible at least by visible light is provided other than the light detection part 2, and each light detection element 2a includes an organic photoconductive film 15 transmissible at least by visible light.SELECTED DRAWING: Figure 1 |
