Abstract:
A liquid crystal display device is provided that includes a pair of substrates which are arranged to face each other with a liquid crystal therebetween, and columnar spacers that are substantially equal in height formed on a liquid-crystal-side surface of one of the pair of substrates, where the columnar spacers include a first columnar spacer which is in contact with a liquid-crystal-side surface of the other substrate of the pair of substrates and a second columnar spacer which is not contact with the liquid-crystal-side surface of that other substrate.
