Provided is a projection type liquid crystal display apparatus, which can
improve black-level display and thus can display a higher-contrast image as compared
to the related art. An optical compensator is located on the light exit side with
respect to the liquid crystal display device so as to compensate for the optical
phase difference caused by liquid crystal molecules in a light-entry-side region
of the liquid crystal layer. As the optical compensator is located on the light
exit side with respect to the liquid crystal display device, birefringence, caused
by the liquid crystal molecules present in the light-entry-side region, is compensated
for without being influenced by a microlenses provided in the liquid crystal plane.
Consequently, the apparatus can improve the black-level display and thus can display
a higher-contrast image as compared to the related art. Further, a phase difference
caused by the birefringence of the nematic liquid crystal molecule is compensated
for by using a substance having properties optically opposite to the positive crystal,
namely, a substance having birefringence equivalent to birefringence of a negative crystal.
