Abstract

The invention discloses a switch element, the preparation method of the switch element, array substrate and display apparatus. The switch element comprises a substrate; a first film transistor arranged on the substrate; and a second film transistor arranged on the first film transistor. The first film transistor consists of a first electrode and a second electrode. The first film transistor and the second film transistor share the first electrode and the second electrode. According to the switch element of the invention, two film transistors are in parallel arrangement with one above the other. This design increases the open-state current of the switch element while reducing the size of the switch element. In addition, as the two film transistors share the same source electrode layer and the drain electrode layer, the preparation technology for the switch element is simplified and the cost is reduced.

Description

technical field [0001] Embodiments of the present invention relate to a switch element, a manufacturing method thereof, an array substrate, and a display device. Background technique [0002] With the development of liquid crystal display technology, current consumers have higher and higher requirements for product resolution, and products with high resolution have gradually become the mainstream of the market, and high resolution means that the charging time for each row of pixels in the device is longer shortening, the corresponding switching element (such as a thin film transistor) needs to increase the on-state current to complete charging and discharging the pixel electrode in a shorter time. In terms of the structural design of the array substrate, the most direct way to increase the on-state current of the switching element is to increase the W / L (width-to-length ratio) of the switching element. For example, a larger W / L can be achieved by increasing the size of a si...
