A color filter substrate and a display device are provided. The color filter substrate comprises a substrate; a color filter layer provided on the substrate; and a photochromic material, the photochromic material and the color filter layer cooperating to display different colors by adjusting the light irradiated onto the color filter substrate. In the color filter substrate and the display device, the photochromic material is introduced into the color filter substrate. In this way, by adjusting the light emitted from the backlight source, the photochromic material is excited to display different colors and the color gamut of the pixel units is thus changed. This color filter substrate and liquid crystal panel can be better applied to different environments.

This disclosure provides a shift register unit comprising an access control module and a shift register module. The access control module is used for controlling access of an input signal and a reset signal. The shift register module is used for outputting the accessed input signal or reset signal under the driving of a clock signal. The access control module comprises a depletion field effect transistor. The shift register unit further comprises a connection control module arranged between the access control module and the shift register module for blocking the connection between the access control module and the shift register module when the shift register module performs outputting. By means of the design of the connection control module in this disclosure, when the shift register unit performs outputting, its high potential leakage path is blocked, so as to reduce the leakage current greatly, and ensure normal output of the shift register unit. This disclosure further provides a gate driving circuit comprising the shift register unit and a display panel comprising the gate driving circuit.
