Abstract
The present invention provides a light guide plate for emitting light radiated from a light source disposed at a side of the light guide plate. The light guide layer has a light incidence side for internally introducing light emitted from the light source at the side thereof; a polarization separation layer comprising a first matrix layer and a first fiber having birefringence and disposed more toward the light emission side than the light guide layer; a low refractive index layer having a lower refractive index than the refractive index of the first matrix layer; and an angle improvement layer comprising a second matrix layer having a second fiber disposed inside the second matrix layer.
