Abstract
Provided is a display device, including: a pair of light transmissive substrates disposed to be opposed to each other at an interval; a sealing member which bonds the pair of light transmissive substrates together and defines an encapsulation space between the pair of light transmissive substrates; a plurality of shutters disposed in the encapsulation space so as to optically display an image; liquid having optical isotropy filled in the encapsulation space; and an optical film disposed between the liquid and at least one of the pair of light transmissive substrates. A refractive index of the optical film is different from a refractive index of the pair of light transmissive substrates.
