PROBLEM TO BE SOLVED: To provide a novel optical modulating element and a display device for which no polarizing plate is used. SOLUTION: This device is composed of two substrates, one of which is transparent at least, arranged while being opposed and a supporting structure for supporting both the substrates and has a cell having the void layer with thickness from 0.05 to 20μm and an outer means capable of changing the thickness of this void layer. Then, this optical modulating element changes the spectrum pattern of light transmitted through or reflected on the cell based on the interference effect of reflected light on two interfaces of the said void layer and both the substrates, and the display device arranges these optical modulating elements in the shape of one-dimensional array or two-dimensional matrix.
