A light guide panel includes: a light guide layer having a light incident surface; a polarization separation layer configured to select a desired polarization among light emitted from the light guide layer and to emit light having the polarization; and a light homogenization layer including a plurality of fibers and a supporting medium of the fibers, the light homogenization layer configured to diffuse and scatter light incident on the light guide layer into the light guide layer. The polarization separation layer includes: a plurality of first fibers having birefringence; and a first supporting medium that is isotropic and configured to support the first fibers. The refractive index of the first supporting medium corresponds to at least one of two different refractive indices of the first fibers. The light homogenization layer includes: a plurality of second fibers having birefringence; and a second supporting medium that is isotropic and configured to support the second fibers.
