PROBLEM TO BE SOLVED: To control alignment of a liquid crystal by using a fine rugged structure formed on a surface in contact with a liquid crystal layer and generating pretilt, in a vertically aligned liquid crystal layer. SOLUTION: A liquid crystal display device 700 includes a pair of substrates, the vertically aligned type liquid crystal layer 490 provided between the pair of substrates, and electrodes 481 and 485 for applying a voltage to the vertically aligned type liquid crystal layer 490. At least one substrate 483 from among the pair of substrates has the rugged structure on a surface which is in contact with the vertically aligned type liquid crystal layer. The surface having the rugged structure formed thereon has a region, in which the height of the rugged structure varies along a first direction with a first period and varies along a second direction perpendicular to the first direction with a second period different from the first period. The first period is not less than 0.1μm and not more than 10μm, and the second period is no less than 0.1μm and not more than 10μm. The vertical alignment type liquid crystal layer 490 has a pretilt, due to the rugged structure with no voltage applied thereacross. COPYRIGHT: (C)2006,JPO&NCIPI
