CROSS-REFERENCE TO RELATED APPLICATION [0001]This application claims priority to and the benefit of Korean Patent Application No. 10-2006-0019282 filed in the Korean Intellectual Property Office on Feb. 28, 2006, the entire contents of which are incorporated herein by reference. BACKGROUND OF THE INVENTION [0002]1. Field of the Invention [0003]The present invention relates to a touch panel for a display device and, more particularly, to a more easily manufactured touch panel. [0004]2. Description of the Related Art [0005]Since a liquid crystal display panel cannot emit light by itself, it is provided with a backlight assembly for emitting light. However, a conventional backlight assembly is separately manufactured from the general display panel and then assembled with the display panel to form a display device. A display device may be provided with a touch panel to enable the user to more easily indicate and obtain specific information. However, the conventional touch panel is separately manufactured and is attached to a display device making the whole process of manufacturing a display device with a touch panel attached complicated and reducing productivity. SUMMARY OF THE INVENTION [0006]According to one aspect of the present invention a more easily manufactured display having a touch panel includes: a base substrate; a first transparent electrode layer located on the base substrate; an ultrasonic wave guiding layer located on the first transparent electrode layer; a second transparent electrode layer located on the ultrasonic wave guiding layer; an ultrasonic wave transmitting unit and an ultrasonic wave receiving unit located on the second transparent electrode layer; and a protecting layer located on the second transparent electrode layer. [0007]The ultrasonic wave transmitting unit may include X-axis transmitting units located along an edge of the base substrate, and Y-axis transmitting units located along another edge adjacent to the edge along which the X-axis transmitting units are located, and the ultrasonic wave receiving unit may include an X-axis receiving unit located along another edge opposite to the X-axis transmitting units, and a Y-axis receiving unit formed along another edge opposite to the Y-axis transmitting units. [0008]The ultrasonic wave guiding layer may be made of a material including at least one of ZnO, Al-doped ZnO (AZO), and polyvinylidenefluoride (PVDF). [0009]According to a second embodiment of the invention, a display device includes: a display panel that has a plurality of pixels and displays an image; and a touch panel located on the front surface of the display panel. In this embodiment, the touch panel includes a base substrate; a first transparent electrode layer located on the base substrate; an ultrasonic wave guiding layer located on the first transparent electrode layer; a second transparent electrode layer located on the ultrasonic wave guiding layer; an ultrasonic wave transmitting unit and an ultrasonic wave receiving unit located on the second transparent electrode layer; and a protecting layer located on the second transparent electrode layer. [0010]In the display device, the ultrasonic wave transmitting unit may include X-axis transmitting units located along an edge of the base substrate, and Y-axis transmitting units located along another edge adjacent to the edge along which the X-axis transmitting units are located, and the ultrasonic wave receiving unit may include an X-axis receiving unit located along another edge opposite to the X-axis transmitting units, and a Y-axis receiving unit located along another edge opposite to the Y-axis transmitting units. [0011]The ultrasonic wave guiding layer may be made of a material including at least one of ZnO, Al-doped ZnO (AZO), and polyvinylidenefluoride (PVDF). [0012]The display panel may include a first display panel located on the rear side thereof, and a second display panel that is located on the front side thereof and is bonded to the first display panel, and the touch panel may be located on the front surface of the second display panel. [0013]The display device may further include a backlight assembly located on the rear surface of the first display panel. [0014]In this structure, the backlight assembly may include a light source substrate, a driving circuit unit located on the light source substrate, an anode connected to the driving circuit unit, an organic layer located on the anode, and a cathode located on the organic layer. [0015]The base substrate, the first display panel, the second display panel, and the light source substrate may be formed of a ceramic material to have rigidity. [0016]Alternatively, the base substrate, the first display panel, the second display panel, and the light source substrate may be formed of a plastic material to have flexibility. [0017]The organic layer may be divided into a plurality of regions corresponding to the pixels of the display panel, respectively, and the driving circuit unit may drive the plurality of regions of the organic layer to individually emit light. [0018]The divided regions of the organic layer may emit three primary color light components. [0019]The display device may further include a first polarizer attached between the rear surface of the first display panel and the backlight assembly, and a second polarizer attached between the front surface of the second display panel and the touch panel. [0020]The display device may further include an additional polarizer attached between the rear surface of the first display panel and the backlight assembly. In this display device, a polarizer may be used as the base substrate of the touch panel. [0021]The second display panel and the base substrate of the touch panel may be integrated into a whole.
