    Abstract: An array substrate manufacturing method and an array substrate are provided. The array substrate manufacturing method uses an organic photoresist material to form a passivation protection layer for substituting the conventional passivation protection layer that is made of a silicon nitride material and applies one mask to subject the passivation protection layer and a planarization layer to exposure and development so as to obtain a third via that is located above the first drain electrode and a fourth via that is located above the second drain electrode and, thus, compared to the prior art techniques, saves one mask and reduces one etching process so as to achieve the purposes of simplifying the manufacturing process and saving manufacturing cost. The array substrate so manufactured has a simple structure and a low manufacturing cost and possesses excellent electrical performance.

    Abstract: The present invention provides a manufacturing method of LTPS array substrate, wherein the LTPS array substrate contains at least a metal mask layer, a buffer layer, an active layer, a gate insulating layer and a gate layer. The manufacturing method is to form the gate layer by patterning the gate layer using the metal mask layer as a photomask, and a width of the formed gate layer is smaller than a width of the metal mask layer so that a vertical projection of the gate layer falls within the scope of the metal mask layer. In the present invention, the cost of producing a metal mask for the gate electrode is saved by patterning the gate layer using the metal mask layer as a photomask, so that the cost of producing LTPS is saved and the process of production is simplified.

    Abstract: The present disclosure relates to a display device and a color filter. The color filter includes a dielectric layer and wire grid structures on the dielectric layer, each of the wire grid structures includes a first wire grid unit, a second wire grid unit, a third wire grid unit, and a fourth wire grid unit. The first wire grid unit, the second wire grid unit, the third wire grid unit, and the fourth wire grid unit respectively includes a plurality of wire grids spaced apart from each other. Grid-spaces of the first wire grid unit, the second wire grid unit, the third wire grid unit, and the fourth wire grid unit are different. With such configuration, the white CIE composited by the R sub-pixel, the G sub-pixel, and the B sub-pixel may be matched with the white CIE of the W sub-pixel.
