The invention discloses a
display device and a manufacturing method of the
display device. The
display device comprises a
total internal reflection substrate, a glass substrate and a light
ray transmission device, wherein the
total internal reflection substrate is used for transmitting light rays to the light
ray transmission device during frustrated
total internal reflection; the glass substrateis used for assembling with the total internal reflection substrate to generate a
light source transmission space and transmitting visible light; and the light
ray transmission device comprises a pixel
electrode and a
control unit of the pixel
electrode, a magnetized ferromagnetic non-light tight material and a color optical filtering
polymer combined with the magnetized ferromagnetic non-light tight material, wherein the color optical filtering
polymer is arranged on the glass substrate, and the light ray transmission device is used for vibrating the color optical filtering
polymer in the
light source transmission space through
magnetic effect when the pixel
electrode is charged to generate an alternative
electric field, and transmits the visible light in light rays out of the glass substrate when the light ray transmission device is close to the total internal reflection substrate. The display device has the advantages of visible full viewing angle, higher
transmittance of the lightrays, energy and power conservation,
lightness and thinness portability, and quick dynamic response speed.
