A substantially cross-shaped column (101) whose every branch has the thickened top is formed in the air gap between scanning electrodes (43) formed in a stripe-shape on a lower surface substrate of a dot matrix liquid crystal display element. Both sides of the top of each lateral branch (parallel with the longitudinal direction of the scanning electrodes (43)) of the column (101) are formed in contact with the surface of the scanning electrodes (43). Other part of the column (101) than the top of each lateral branch and the central portion of the branch are formed in contact with the surface of the lower surface substrate. The lower surface substrate is a plastic film, and the column (101) is an adhesive wall face structure body. Contact force of the column (101) to the surface of the scanning electrodes is greater than that to the surface of the lower surface substrate (resin surface of the plastic film).
