Abstract
The invention provides an array substrate and a display device. The array substrate and the display device are used for solving the problems that orientation liquid of an array substrate in the prior art is uneven in diffusion, and a boundary cannot be defined. A flow-guiding groove which can make the surface of the edge of the orientation liquid be distributed evenly and is used for flow guiding of the orientation liquid is formed in a frame region of the array substrate, and the surface tension of the orientation liquid caused by the uneven location (corresponding to the location of a via hole) of the array substrate is released, so that the orientation liquid in the frame region and a display region is even and equal. In addition, the maximum outward-diffusing boundary of the orientation liquid is limited by the flow-guiding groove, the boundary of the orientation liquid can be controlled, and all kinds of bad situations caused by overflowing of the orientation liquid are prevented.
