Abstract

The invention provides an array substrate and a display device. The array substrate and the display device are used for solving the problem that due to the fact that the difference between the feature of a thin film transistor in a detection area and the feature of a thin film transistor in a display area is large, the detection accuracy is low. The array substrate comprises a display area and a pseudo pixel area located on the periphery of the display area. A second pixel unit is arranged in the pseudo pixel area which comprises at least one detection unit. Each detection unit comprises a second pixel unit. Each second pixel unit is correspondingly provided with one thin film transistor. All electrodes of all the thin film transistors are respectively connected with external testing equipment through testing wires.

Description

technical field [0001] The present invention relates to the technical field of display devices, in particular to an array substrate and a display device. Background technique [0002] The array process is a stage in the manufacturing process of a Thin Film Transistor Liquid Crystal Display (TFT-LCD) device. In the array process, it is necessary to form a thin film transistor array circuit on a glass substrate. The quality of the array circuit directly determines the quality of the thin film transistor liquid crystal display, and the detection of the array circuit has become an important process in the manufacturing process. [0003] Such as figure 1 As shown, the array substrate 100 includes: a display area 101 , a routing area 102 and a peripheral area 103 in the early stage of fabrication. The display area 101 includes a plurality of first pixel units for display formed by staggered gate lines and data lines, and each of the first pixel units corresponds to a thin film ...
