The invention discloses an array substrate and a display device, and relates to the technical field of fingerprint detection. The array substrate comprises an optical fingerprint detection circuit, ascanning line, a reading line and a first shielding line which are arranged in an array. The first shielding wire is connected with a ground end. The distance between the first shielding line and thereading line is relatively short; therefore, the coupling noise generated by the detection signal in the reading line and the driving signal input to the light-emitting element in the array substratecan be coupled to the first shielding line; therefore, the coupling noise can be transmitted to the ground end through the first shielding line, that is, the coupling noise can be shielded by the first shielding line, detection signals transmitted to the fingerprint identification circuit by the reading line cannot be interfered, the imaging quality of fingerprints is good, and the fingerprint identification accuracy is high.
