A liquid crystal display device has: a light source, a light guide plate for causing light from the light source to enter from a side surface of the light guide plate and exit as illuminating light from one principal surface thereof; a liquid crystal panel which includes a reflective color filter having wavelength selectivity in transmittance and reflectance and a polarizing plate disposed on a side that is closer to the light guide plate than the reflective color filter, and which is disposed on a light path of the illuminating light; and a recycle part for reflecting the illuminating light that has been reflected by the reflective color filter toward the reflective color filter once again, wherein the light from the light source is configured to enter the light guide plate as approximately linear polarization, and the polarizing plate of the liquid crystal panel is configured so exhibit transmittance of 90% or higher.
