ABSTRACT:
A liquid crystal display apparatus having an input function includes a first substrate, a second substrate, and a third substrate; a display medium provided between the first substrate and the second substrate; a first electrode provided between the first substrate and the display medium; a second electrode provided between the second substrate and the display medium; spacers for supporting the second substrate and the third substrate with respect to each other; and at least two electrodes provided between the second substrate and the third substrate. The display medium includes a polymer projection and a liquid crystal region at least partially surrounded by the polymer projection, and the first, second and third substrates are each formed of a polymer material, at least one of the first, second and third substrates has a polarizing function, and at least one of the first, second and third substrates has a phase contrasting function.
