PROBLEM TO BE SOLVED: To provide a matrix type picture display device capable of displaying even a plurality of pictures whose signal formats are different on a composite screen. SOLUTION: A panel 170 is divided into two blocks 170a, 170b since row electrodes are divided roughly at the center part of the left and right side of the panel. Driving circuits which are respectively constituted of S/P conversion circuits 14a, 14b, pulse width modulator/drivers 15a, 15b and scanning drivers 16a, 16b and video signal processing circuits which process video signals which are to be displayed by the driving circuits and which are respectively constituted of decoders 11a, 11b to control circuits 13a, 13b are respectively provided with respect to the blocks 170a, 170b. Since this display device has horizontal and vertical compressing and expanding circuits 18a, 18b in the video signal processing circuits, video signals are compressed or expanded in accordance with the pixels of the panel 170.
