Abstract

The embodiment of the invention provides an array substrate, a dual field of view display device and a manufacturing method thereof, relating to the field of display technology. The array substrate comprises a plurality of pixel units divided by grid lines and data lines which are crossed vertically and horizontally. Each pixel unit comprises a pixel electrode and a TFT circuit, wherein the pixel electrode of each pixel unit comprises at least two first pixel electrodes and at least two second pixel electrodes which are mutually spaced, and the TFT circuit of each pixel unit comprises a first sub TFT circuit connecting with the first pixel electrode and a second sub TFT circuit connecting with the second pixel electrode. The above array substrate is used by the dual field of view display device. Since the above array substrate is used, a double vision baffle can be made in the display device, adding a new working procedure or employing new production equipment is avoided, thus production cost is reduced. The embodiment of the invention is used for manufacturing the dual field of view display device.
