Patent abstract
In a liquid crystal display device having a pair of substrates that are opposite to and bonded to each other, a liquid crystal layer is sealed between the pair of substrates, and columnar spacers are formed on one of the pair of substrates and in contact with the other substrate to maintain a gap between the pair of substrates. The surfaces of support columns of the columnar spacers are made to be rough to enhance the friction force between the pair of substrates and to prevent the other of the pair of substrates from diverging from the one of the pair of substrates, so that display quality of the liquid crystal display device is improved.
