A dual display type portable computer can include a first unit having a first display module and a second unit rotatably coupled to the first unit having a second display module. At least one hinge unit can couple the first unit and the second unit with each other. The hinge unit can be coupled to corresponding positions of the first unit and the second unit to enable the first display module and the second display module to overlap each other or to be unfolded until they are placed in an equal plane. Preferably, at least one of the first display module and the second display module has a touch screen function. Preferably, the touch screen function can selectively change a language of a keyboard image. The first display module and the second display module can display different images or divided portions of one integrated image.
