Abstract: Disclosed is a display device that is capable of being driven with low power consumption. A first thin-film transistor including a polycrystalline semiconductor layer and a second thin-film transistor including an oxide semiconductor layer are disposed in an active area, thereby reducing power consumption. At least one opening formed in a bending area is formed to have the same depth as any one of contact holes formed in the active area, thereby making it possible to form the opening and the contact holes through the same process and consequently simplifying the process of manufacturing the device. A second source electrode of the second thin-film transistor and a second gate electrode of the second thin-film transistor overlap each other with an upper interlayer insulation film interposed therebetween so as to form a first storage capacitor.

Abstract: Disclosed is a display device that with low power consumption. The display device includes a first thin film transistor having a polycrystalline semiconductor layer in an active area and a second thin film transistor having an oxide semiconductor layer in the active area, wherein at least one opening disposed in a bending area has the same depth as one of a plurality of contact holes disposed in the active area, whereby the opening and the contact holes are formed through the same process, and the process is therefore simplified, and wherein a high-potential supply line and a low-potential supply line are disposed so as to be spaced apart from each other in the horizontal direction, whereas a reference line and the low-potential supply line are disposed so as to overlap each other, thereby preventing signal lines from being shorted.

Abstract: Disclosed are a display device and a method for driving a pixel of the display device. The device and method is capable of securing a time to sense a threshold voltage of a driving transistor and of compensating for the threshold voltage during operation of the pixel. Each of a plurality of pixels has a 5T1C structure including first to fourth transistors and a driving transistor. The first to fourth transistors are configured to apply driving signals through first to fourth scan lines, respectively. Thus, even without increasing the number of driving signals applied to each pixel, a long time for sensing a threshold voltage of each pixel can be secured.
