Abstract The purpose of the present invention is to provide a method for manufacturing a liquid crystal display device which can easily remove a removal part even from the liquid crystal display device using substrates made of thermoplastic resin. The liquid crystal display device is constructed by sticking the first and second substrates made of thermoplastic resin to each other using a sealing material. A dividing line is formed on the first substrate by a dicing method which is a half cut with a predetermined remaining thickness so that the removal part within the first substrate becomes easy to be removed. A jet of compressed air is emitted into between the first substrate the half cut is performed on and the second substrate so as to lift up the removal part. The jet of compressed air is emitted in the diagonal direction toward the liquid crystal display device. When the jet of compressed air is emitted, a removal head is inserted between the removal part and a terminal area so as to remove the removal part.
