ABSTRACT:
A liquid crystal display device includes, from its back surface side towards its front surface side: a polarization selective reflection plate (12) which reflects x-directional linearly polarized light and transmits y-directional linearly polarized light; a first polarizing plate (4) which transmits the x-directional linearly polarized light; a liquid crystal display panel (13); and a second polarizing plate (8) which transmits the y-directional linearly polarized light. The polarization selective reflection plate (12) is arranged only on a back surface side of the liquid crystal display panel (13). The y-directional linearly polarized light incident on the back surface side is reflected from the polarization selective reflection plate (12), there by protecting privacy. The x-directional linearly polarized light transmitted reaches the front surface side, via the first polarizing plate (4), the liquid crystal display panel (13), and the second polarizing plate (8). In this way, it is possible to realize a liquid crystal display device which is capable of performing a good screen displaying even under a strong surrounding light environment.
