Abstract

A liquid crystal display apparatus including: a first substrate; a second substrate arranged opposite the first substrate; and a liquid crystal layer held between the first substrate and the second substrate; further provided with a plurality of scanning lines arranged over the first substrate; signal lines arranged over the first substrate to cross the scanning lines; pixels each composed matching an area surrounded by the scanning lines and the signal lines; pixel electrodes arranged over the first substrate and matching the signal lines; and common electrodes arranged over the first substrate and matching the pixel electrodes, wherein at least either of the first substrate and the second substrate is provided with unevenness to vary the thickness of the liquid crystal layer in the light-transmissive regions of the same ones of the pixels.
