Zusammenfassung:	Conventionally, in a transparent display area, a gradation value of each color component is assigned to transparent gradation. Hence, when video is displayed in a video display area, each color component can only be represented in gradations with a gradation value of 0 to 1022, and it becomes necessary to assign pixel values to the transparent gradation. Accordingly, a color represented by those pixel values cannot be displayed. In view of this, by adding transparent area information to a vertical blanking period of a video signal, the pixel values can also be used to display video. By this, each of the color components can be represented in gradations with a gradation value of 0 to 1023, and thus, video can be displayed in full-range color even when a transparent display area is provided.
