Abstract: A display device includes a display unit for displaying an image, a first retarder provided on the display panel, a first polarizing plate provided on the first retarder, a touch unit provided on the first polarizing plate, a second retarder provided on the touch unit, and a second polarizing plate provided on the second retarder. With this arrangement, external light entering into the display may either be transmitted or reflected off of the touch unit, and in either case, be absorbed by the second polarizing plate without leaving the display device.

Abstract: A shift register that is capable of performing partial driving and a display device having the shift register, in which the shift register has at least two display regions, each of which includes pixels and signal lines connected thereto. The shift register includes at least two stage groups, each of which includes a plurality of stages connected to each other to sequentially generate output signals, wherein each stage group transmits the output signals to the signal lines included in one of the two display regions. Accordingly, the shift register is divided into a plurality of the stage groups, and only the necessary portion of a screen can be displayed, so that it is possible to reduce power consumption.

Abstract: A liquid crystal display includes a first panel unit; a second panel unit; a first flexible printed circuit film (FPC) having an opening exposing the second panel unit; a light source unit providing the first and the second panel units and including a plurality of lamps; and a current controller controlling a current applied to the light source unit and including a capacitoritor is less than 100 nF.
