Embodiment 1

[0033] An embodiment of the present invention provides a display substrate. The display substrate is provided with: a blue-phase liquid crystal layer; and driving electrodes for driving the blue-phase liquid crystal layer in a dark state. Each group of driving electrodes includes two There are two opposite electrodes, and the components of the electric field generated by the two opposite electrodes in the blue phase liquid crystal layer in the first direction are not zero, and the first direction is perpendicular to the polarization direction of the incident light.

[0034] An embodiment of the present invention provides a display substrate, which is suitable for a flat field display device. The flat field display device mentioned here means that the electric field used to drive liquid crystal deflection for display is a parallel electric field parallel to the substrate. At present, there are mainly: plane switching technology (In-Plane Switching, referred to as IPS), Advanced ...

Abstract

The embodiment of the invention discloses a display baseplate as well as a manufacture method thereof and a display device, and relates to the field of display. Dark state light leak can be reduced; the display quality of the device can be improved. The display baseplate is provided with a blue phase liquid crystal layer and driving electrodes used for driving the blue phase liquid crystal layer in the dark state; each group of driving electrodes comprises two out-of-phase electrodes; the component in a first direction of electric field generated by the two out-of-phase electrodes on the blue phase liquid crystal layer is not zero; the first direction is perpendicular to the polarization direction of incident light.

Description

technical field [0001] The invention relates to the display field, in particular to a display substrate, a manufacturing method thereof, and a display device. Background technique [0002] Advanced-Super Dimensional Switching (abbreviation: ADS) forms a multi-dimensional electric field through the parallel electric field generated by the edge of the pixel electrode or the common electrode in the same plane and the vertical electric field generated between the pixel electrode and the common electrode, so that the liquid crystal cell All alignment liquid crystal molecules between the inner pixel electrodes or the common electrodes, and directly above the pixel electrodes or the common electrodes can produce rotation conversion, thereby improving the working efficiency of the plane alignment liquid crystal and increasing the light transmission efficiency. Advanced ultra-dimensional field switching technology can improve the picture quality of TFT-LCD, and has the advantages of ...
