Abstract

The invention provides a display substrate. The display substrate comprises a substrate base plate and a plurality of pixel units located on the substrate base plate. Each pixel unit comprises two first sub-pixels, a second sub-pixel and a third sub-pixel, each sub-pixel comprises a storage capacitor which comprises a first polar plate and a second polar plate which are oppositely arranged, through holes are formed in the second polar plates, and the first sub-pixels further comprise shielding metal structures arranged corresponding to the through holes; in the first sub-pixels, the shieldingmetal structures are connected with the second polar plates; the orthographic projections of the second polar plates and the shielding metal structures on the substrate base plate cover the orthographic projections of the first polar plates on the substrate base plate, and the orthographic projections of the shielding metal structures on the substrate base plate cover the orthographic projectionsof the through holes on the substrate base plate. The invention further provides a display device.

Description

technical field [0001] Embodiments of the present disclosure relate to the field of display technologies, and in particular, to a display substrate and a display device. Background technique [0002] The GGRB pixel structure is one of the mainstream pixel structures currently used in Organic Light-Emitting Diode (OLED) display devices, that is, each pixel of an OLED display device includes a green sub-pixel G, a green sub-pixel G, a red sub-pixel Subpixel R and blue subpixel B. [0003] In each pixel of the OLED display device, the film layer structures in the two green sub-pixels G are inconsistent, resulting in a brightness difference between the two green sub-pixels G, specifically, in the two green sub-pixels G, The inconsistency of the parasitic capacitance between the storage capacitor and the anode leads to a brightness difference between the two green sub-pixels G. For the entire OLED display device, the brightness difference between the green sub-pixels G is likely...
