Abstract

The embodiment of the invention provides an array substrate, the array substrate comprises a first TFT device and a second TFT device, the first TFT device at least comprises a first grid electrode, a first source electrode and a first drain electrode, and the second TFT device at least comprises a second grid electrode, a second source electrode and a second drain electrode, at least one of the first grid electrode, the first source electrode and the first drain electrode and at least another one of the second grid electrode, the second source electrode and the second drain electrode are arranged on the same layer; according to the invention, the film layers between different TFT devices are arranged on the same layer, so that at least one photomask can be reduced.

Description

technical field [0001] The present application relates to the field of display technology, in particular to an array substrate. Background technique [0002] In LTPO technology, the first gate and the first source / drain of the low-temperature polysilicon TFT device are fabricated separately, and the second gate and second source / drain of the oxide TFT device are also fabricated separately. Many, the overall production cost is relatively high. [0003] Therefore, the existing array substrate has the technical problem of separate preparation of gates and source / drain electrodes of different TFT devices, resulting in many photomasks and high cost. Contents of the invention [0004] The embodiment of the present application provides an array substrate, which can alleviate the technical problems of the existing array substrate that gates and source / drain electrodes of different TFT devices are separately prepared, resulting in many photomasks and high cost. [0005] An embodi...
