An optical sheet member and a display device. The optical sheet member comprises the following: a light-converting sheet containing a fluorescent material that absorbs light in at least part of the 380-480 nm wavelength band, converts said light to longer-wavelength light, and re-emits said longer-wavelength light; and a wavelength-selective reflective polarizer that functions in at least part of the 380-480 nm wavelength band. When incorporated into a display device that uses a backlight that emits light containing at least blue wavelengths, this optical sheet member improves the frontal luminance and color-reproduction range of said display device. |
