摘要： A display including a plurality of pixels each including a plurality of first subpixels and a plurality of second subpixels. In pixel, when illumination light is applied to the first subpixels from a normal direction, no diffracted light emerges from the plurality of first subpixels, or first diffracted light emerges from the plurality of first subpixels in a first angular range. When illumination light is applied to the second subpixels from the normal direction, no diffracted light emerges from the plurality of second subpixels, or second diffracted light having a wavelength equal to that of the first diffracted light emerges from the plurality of second subpixels in a second angular range wider than the first angular range, at an intensity lower than that of the first diffracted light; with the pixels configured to display a continuously changing image using the first diffracted light and the second diffracted light.
