Abstract
A method for applying the sealing material onto the corner regions of the substrate to realize the liquid crystal cell with large display region. A protrude region 100 is formed on each of the side regions adjacent to a display region of a first substrate 20. A difference of level is formed at each boundary of the side region and the corner region on one surface of the first substrate 20 for providing the corner region with a height which is lower than a height of the side region. A sealing material 30 is applied on the side regions and the corner regions on the one surface of the first substrate 20 by a tool for dispensing the sealing material 30. When a second substrate 10 is positioned on the applied sealing material 30 on one surface of the first substrate 20, a distance between the first substrate 20 and the second substrate 10 is decreased and the sealing material 30 applied on the first substrate 20 is collapsed.
