Abstract: PROBLEM TO BE SOLVED: To obtain a method for coating a corner area of a substrate with a sealant so that a liquid crystal cell can have a wide display area. SOLUTION: A projected part 100 is provided in the area of a side of one surface of a 1st substrate 20 and given a step so that the top surface of the corner area is lower. Using dispenser, the side area and corner area is coated with a sealant 30 along the circumference of the 1st substrate 20. When a 2nd substrate is put on the 1st substrate 20, the applied seal material 30 collapses, but the spread of the inside edge 36 of the sealant becomes smaller in the corner area of the liquid crystal cell because the step exists. This method prevents the sealant 30 from spreading inward in the corner area and the sealant can be formed while being controlled into a frame shape closely to the display area 13, so a wider display area than before can be realized.
