A display device includes: a first member including a light emitting unit to emit light; a second member disposed on the first member; and a display panel disposed on the second member. The second member includes: a base substrate; a fiber diffusion layer disposed on the base substrate and including a nonwoven fabric; and a filter layer disposed under the base substrate and facing the first member, the filter layer having a reflectance and a transmittance, which vary depending on an incident angle of light of a specific wavelength. The base substrate has a thermal expansion coefficient lower than thermal expansion coefficients of the fiber diffusion layer and the filter layer.
