An array substrate and a display device are disclosed. The array substrate includes a base substrate, a plurality of gate lines and a plurality of data lines arranged to intersect each other on the base substrate, a pixel electrode arranged in a region defined by an adjacent gate line and an adjacent data line, and a thin film transistor arranged at an intersection of the gate lines and the data lines. A drain of the thin film transistor is connected with the pixel electrode through a via hole. The gate lines further include a widening portion between adjacent data lines. The widening portion comprises a recess structure. An orthogonal projection of the recess structure on the base substrate at least partly overlaps that of the drain of the thin film transistor on the base substrate.

The present invention relates to liquid-crystalline media (LC media) having negative or positive dielectric anisotropy comprising self-aligning mesogens (SAMs) which effect homeotropic (vertical) alignment of the LC media at a surface or the cell walls of a liquid-crystal display (LC display). The invention therefore also encompasses LC displays having homeotropic alignment of the liquid-crystalline medium (LC medium) without conventional imide alignment layers. The LC media may be supplemented by a polymerisable or polymerised component, which serves for stabilisation of the alignment, for adjustment of the tilt angle and/or as passivation layer.
