Abstract
A liquid crystal display apparatus including first and second substrates which are disposed facing each other, with liquid crystal sealed between said first and second substrates, a first electrode formed on the first substrate and a second electrode formed on the second substrate. There are alignment control layers covering the first and second electrodes, wherein the alignment control layers control the alignment direction of liquid crystal molecules, when no voltage is applied, to be roughly vertical to faces of the first and second substrates. Bumps are formed on at least one surface of the first and second substrates, wherein the bumps determine tilting directions of the liquid crystal molecules when voltage is applied. Both of the alignment control layers and the bumps are made of a polymerizable compound included in and mixed with said liquid crystal.
