Abstract
Disclosed is a display device which obviates the need for a space to mount an additional sub display, so that a product is made slim and compact. The display device includes an LCD panel or e-paper for displaying main information, a TOLED panel formed on the LCD panel or e-paper and displaying sub information, a touch panel formed on the TOLED panel, and a controller electrically connected to the LCD panel or e-paper, the TOLED panel and the touch panel, in which the controller applies driving voltage to the LCD panel or e-paper so that main information is displayed through the LCD panel or e-paper when an electrical signal of the touch panel is sensed, and applies driving voltage to the TOLED panel so that sub information is displayed through the TOLED panel when the LCD panel or e-paper is off.
