OPTICAL MODULATION UNIT AND STEREOSCOPIC DISPLAY DEVICE COMPRISING SAME

WIPO Patent Application WO/2014/133269

A1

The present invention provides, for an optical modulation unit of which the manufacturing is simplified and the performance is improved and a stereoscopic display device having the same, an optical modulation unit and a stereoscopic display device comprising the same, the optical modulation unit comprising: a liquid crystal cell having different phase delay amounts of penetrated light in the on and off states; and a phase delay film part arranged on at least one among an optical path of light having passed through the liquid crystal cell and an optical path of light entering into the liquid crystal cell, and comprising a phase delay film having a fixed phase delay amount, wherein when a wavelength of light, which has passed through both the liquid crystal cell and the phase delay film part, is λ, a phase delay amount of the light having passed through both the liquid crystal cell and the phase delay film part is λ/4 when the liquid crystal cell is in the on state and -λ/4 when the liquid crystal cell is in the off state, or is -λ/4 when the liquid crystal cell is in the on state and λ/4 when the liquid crystal cell is in the off state.
