Abstract:
1. A stereoscopic display device comprising: a display panel having a display screen on which two-dimensional image is display, and configured to polarize image light of the image-displaying into a particular polarization direction; and a lens array element disposed to oppose the display screen of the display panel, and having a liquid crystal layer which includes liquid crystal molecules having a refractive index anisotropy and aligned in a predetermined orientation direction under no application of voltage, the lens array element being configured to electrically change the alignment of the liquid crystal molecules to generate a lens effect, and configured to selectively change a state of passing therethrough of the image light exiting from the display panel, wherein the lens array element includes; a first substrate and a second substrate which are disposed to oppose each other and sandwiching the liquid crystal layer therebetween; a first alignment film provided on the first substrate on a side contacting, the liquid crystal layer, and applied with a rubbing process in a first direction; and a second alignment film provided on the second substrate on a side contacting the liquid crystal layer, and applied with a rubbing process in a second direction which is antiparallel to the first direction, and wherein the predetermined orientation direction of the liquid crystal molecules is defined by the first direction and the second direction in the rubbing processes to the first alignment film and the second alignment film, and the first direction and the second direction in the rubbing processes to the first alignment film and the second alignment film are parallel to the polarization direction of the image light.
