PROBLEM TO BE SOLVED: To provide a spectroscopic measurement device which can measure colors at a plurality of places at the same time without luminous colors from adjacent areas superposing even when the object of measurement is a self-luminous object.SOLUTION: A spectroscopic measurement device 20 has: a pinhole array board 5 (area dividing means) for dividing the measurement object area of a display device 1 that is a self-luminous object as the object of measurement by openings optically formed in shape of an array; a microlens array board 4 (image forming means) for condensing area-divided light from the display device 1 that has passed through the array-shaped openings, the microlens being formed in shape of an array; a diffraction grating board 3 (spectroscopic means) for separating the light condensed by the microlens array board 4, having passed through the array-shaped openings, and area-divided by each opening so that diffraction images will not overlap; a line sensor 2 (light-receiving means) for receiving each separated light and formed in shape of an array; and a pinhole array board 5 (optical path length fixing means) for restricting the distance between the pinhole array board 5 and the display device 1.SELECTED DRAWING: Figure 1 |
