摘要 |
A double-sided display device is provided which includes: a light source; a polarized light guide having a first layer having an incident surface which receives light from the light source and which guides the light; a second layer formed on the first layer of an optically isotropic material, on which beam out-coupling units are repeatedly arranged; and a third layer formed of an optically anisotropic material disposed on the second layer, which polarizes and out-couples light illuminated from the light source; and a double-sided display panel which displays images on both sides using the light out-coupled from the polarized light guide.
