Abstract: An optical member, a polarization member, and a display device are provided. The optical member includes a substrate, and a functional layer provided on the substrate, the functional layer including a high refractive layer and a low refractive layer, wherein the high refractive layer has a higher refractive index than that of the substrate and a diffraction grating structure, and the low refractive layer has a lower refractive index than that of the high refractive layer, wherein an interface between the substrate and the high refractive layer and an interface between the high refractive layer and the low refractive layer are in states in which components of the respective layers with the respective interfaces therebetween are compatible with each other.

Abstract: Provided are a light source device, a light emission control method, and a computer program for mitigating flickers. The light source device includes a plurality of light sources, and a controller configured to individually control the plurality of light sources to emit light. The controller controls one or more of the plurality of light sources to emit light at random in a time domain or controls such that light emission timings of the plurality of light sources do not overlap.
