Abstract
Provided are an array substrate and display device. The array substrate includes a base substrate; a fingerprint recognition unit with a light sensing structure; a light blocking layer and an electrode connecting structure arranged at a side of the light sensing structure facing away from the base substrate. The light blocking layer is provided with a collimation hole. A vertical projection of the collimation hole on the base substrate is partially overlapped with a vertical projection of the light sensing structure on the base substrate. An insulation layer is arranged between the electrode connecting structure and the light sensing structure. The insulation layer is provided with an electrode via. The electrode connecting structure is connected to the light sensing structure through the electrode via. The vertical projection of the collimation hole on the base substrate is not overlapped with a vertical projection of the electrode via on the base substrate.
