There is a method of dividing a screen into the expression technique of TVCM and showing it two or more images simultaneously. It is the so-called "Split-Screen." It is used for looking forward to the trial of graphic design with emphasis of the goods characteristic, extension of an image, a figurative expression, and so on. For the background according to which a split screen is introduced into TVCM, social and technical backgrounds, such as increase of the amount of information, improvement in the speed of action or thinking, and enlargement of the accuracy of a television set, can be considered. Furthermore, restrictions of the time given to TVCM and demands from a sponsor are also one of the reasons. Moreover it is also a fact that the environment of the work which can perform screen division and composition easily has been improved. However, a "Split-Screen" must not cause a audience's visual confusion, and it must carry out usage which considered the message and expressional adjustment, and the suitable effect of communication of TVCM.
