To provide a manufacturing method of a reflection type liquid crystal display element by which a glass substrate and silicon substrate laminated on each other are cut without causing any chipping.

The reflection type liquid crystal display element 8 is obtained by applying a sealing adhesive 3 so as to surround an image display area 2 of the silicon substrate 1 to form a region surrounded by the sealing adhesive 3, oppositely arranging the glass substrate 5 apart the prescribed spacing provided on the image display area side of the silicon substrate 1, laminating both the substrates on each other, and cutting the silicon substrate 1 and the glass substrate 5 in an image display area 2 unit. The cutting is performed by using a CO2 laser beam. Glass bits 7 are produced by cutting only the glass substrate 5 along the outer periphery of the sealing adhesive 3 from the glass substrate 5 side and the glass substrate 5 other than the glass bits 7 made to remain on the silicon substrate 1 is removed. The silicon substrate 1 is then cut along the outer periphery of the sealing adhesive 3 by using a YAG laser beam.
