Abstract: The purpose of the invention is to form a stable oxide semiconductor TFT in a display device. The concrete structure is: A display device having a TFT substrate that includes a TFT having an oxide semiconductor layer comprising: the oxide semiconductor layer is formed on a first insulating film that is formed by a silicon oxide layer, the oxide semiconductor layer and an aluminum oxide film are directly formed on the first insulating film. The first insulating film becomes oxygen rich when the aluminum oxide film is formed on the first insulating film by sputtering. Oxygens in the first insulating film is effectively confined in the first insulating film, eventually, the oxygens diffuse to the oxide semiconductor for a stable operation of the oxide semiconductor TFT.

Abstract: The power consumption of a shift register or a display device including the shift register is reduced. A clock signal is supplied to a shift register by a plurality of wirings, not by one wiring. Any one of the plurality of wirings supplies a clock signal in only part of the operation period of the shift register, not during the whole operation period of the shift register. Therefore, the capacity load caused with the supply of clock signals can be reduced, leading to reduction in power consumption of the shift register.

Abstract: Liquid crystal display devices and backlight driving methods thereof are provided. A backlight module of the liquid crystal display device includes a light-emitting unit, a calculation unit, a comparison unit, and a control unit. The calculation unit calculates a first preset backlight brightness value of a backlight partition according to a partition average brightness value and a partition maximum brightness value of a corresponding display partition under a current frame display image. The comparison unit compares a second preset backlight brightness value of the backlight partition under a previous frame display image and the first preset backlight brightness value, and outputs a comparison result. The control unit outputs a first brightness driving value of the backlight partition under the current frame display image according to the comparison result. The light-emitting unit emits light in the backlight partition according to first brightness driving value.
