Display module, and cellular phone and electronic device provided with display module

摘要

It is an object to achieve downsizing and a thin shape of a display module and an electronic device provided with the display module. The display module includes a first display panel in which a first display screen is formed on one main side; and a second display panel that is smaller than and overlapped with the first display panel, in which a second display screen is formed on an opposite side of the one main side. The display module includes, over a sealing substrate of the first display panel and/or the second display panel, at least one integrated circuit, which is connected to input terminals of the first display panel and the second display panel and controls operation of the both panels, arranged in a peripheral portion of the second display panel, which is a surface on an opposite side of a display surface of the first display panel.
