There is disclosed a contact structure for electrically connecting conducting lines formed on a first substrate of an electrooptical device such as a liquid crystal display with conducting lines formed on a second substrate via conducting spacers while assuring a uniform cell gap among different cells if the interlayer dielectric film thickness is nonuniform across the cell or among different cells. A first conducting film and a dielectric film are deposited on the first substrate. Openings are formed in the dielectric film. A second conducting film covers the dielectric film left and the openings. The conducting spacers electrically connect the second conducting film over the first substrate with a third conducting film on the second substrate. The cell gap depends only on the size of the spacers, which maintain the cell gap.
