Display apparatus with a reflective polarizer including microfiber yarns

摘要

An optical body (140) for a display apparatus (500) which can improve brightness of a display apparatus (500) and a display apparatus (500) are provided. The display apparatus (500) includes a light source (50), a display panel (400) that receives light from the light source (50) and displays an image, and an optical body (140) positioned between the light source (50) and the display panel (400), wherein the optical body includes an optical layer (141) including a plurality of microfiber yarns (144) having refractive index anisotropy, and pitches of the plurality of microfiber yarns (144) are set based by the wavelength of the light to be transmitted or reflected.
