To make a sealing width uniform, without the generation of spacer column foam in a seal at single-substrate sealing of liquid crystal cells with sealing material by providing the device with columnar spacers, exclusive of regions where the sealing material spreads at sealing stage.

A sealing material 24 is applied at the region which is the pixel region circumference of a first substrate, formed with the columnar spacers 26 and sealing part columnar spacers 27 and is apart by 500 μm from the columnar spacers 26 exclusive of an injection port, in such a manner that a width of 300 μm is set. As a result, the single-substrate sealing for heating the sealing material 24 by one sheet each is executed, in order to improve the gap accuracy of the liquid crystal cell 20a, with which the spacing is uniformly held by the columnar spacers 26 and to shorten the sealing stage time. Even if the width thereof is rapidly increases, the columnar spacers 26 are not arranged in a region where the sealing material 24 spreads, and therefore, the remaining spacer column foam in the sealing material 24 does not occur in spite of the rapid spreading of the sealing material 24 and the stable sealing width can be obtained. Then, a good satisfactory sealing free from peeling is obtained.
