。However, since the insulating material P coating exists on the leads, the contact resistance of the leads becomes extremely large. In addition, since the film of the P process is a thin film with a thickness of 500 8 or less, the contact resistance varies widely due to the large number of pin poles. However, masking only the lead portions when forming the alignment film poses problems in workability and is extremely costly.
