Embodiment 1

[0058] An embodiment of the present invention provides an array substrate, such as figure 1As shown, it includes a base substrate 1, a thin film transistor unit 2 located on the base substrate 1, a color filter 4 and a flat protective layer 3, and the flat protective layer 3 is connected to the drain 25 of the thin film transistor unit 2 electrical connection, wherein the flat protective layer 3 is conductive.

[0059] Wherein, the flat protective layer 3 formed on the array substrate is usually formed by a resin with a certain viscosity, which can flatten the uneven structure on the array substrate, and protect the structure under the flat protective layer 3 from being damaged. Corrosion, to ensure that the subsequent manufacturing process of the array substrate can be carried out smoothly.

[0060] But in the embodiment of the present invention, the flat protective layer 3 can also conduct electricity, so that the flat protective layer 3 can not only play the role of flat p...

Embodiment 2

[0106] The embodiment of the present invention provides a method for preparing the array substrate described in Embodiment 1, such as Figure 10 Shown, this preparation method comprises:

[0107] Step S101 , forming a pattern including a drain of a thin film transistor unit, a color filter and a flat protection layer electrically connected to the drain of the thin film transistor unit.

[0108] Thus, it is possible to form Figure 1-Figure 7 The shown flat protective layer 3 is electrically connected to the array substrate with the drain electrode 25 . Specifically, it can be known from Embodiment 1 that the array substrate provided by the embodiment of the present invention is at least as Figure 1-7 In the seven structures shown, that is, the drain 25 of the thin film transistor unit 2 can be either above the flat protective layer 3 or below the flat protective layer 3, and the thin film transistor unit 2 can be a bottom gate type Also available as top gate type.
