An array substrate and a display device and method of preparation

Embodiments of the present invention provides an array substrate and a display device and method of preparation. Partitioning the plurality of sub-pixels of the array substrate includes a base substrate, the substrate disposed on the substrate, and the substrate disposed on the substrate in each of the sub-pixel phase transfer pattern, the phase transfer pattern is provided to make generating phase shift the light passing through the phase transfer pattern, whereby a phase transfer position of the pattern corresponding to the substantially opaque. The phase transfer pattern may be greatly reduced such that the lateral leakage of light, and may be such that the transmittance of product uniformity, thereby greatly increased and its stability.
