Abstract
In a liquid crystal display device, positional shifts in patterns formed on an upper substrate and a lower substrate are reduced. The liquid crystal display device is arranged by one pair of substrates whose thermal expansion coefficients are different from each other, the substrates being mutually attached to each other via a predetermined space, predetermined patterns formed on inner surfaces of the respective substrates and positionally aligned to each other, a dimension of one pattern being previously and adjustably set with respect to a dimension of the other pattern based upon a difference existing in the thermal expansion coefficients of the paired substrates; and liquid crystal held in the predetermined space defined by the paired substrates.
