Array substrate, display panel, display device and preparation method of array substrate

The invention relates to the field of display, and discloses an array substrate, a display panel, a display device and a preparation method of the array substrate. The array substrate comprises: a lining substrate; a light blocking layer formed on one side of the lining substrate and made of a flexible material; a first blocking layer formed on one side, deviating from the lining substrate, of thelight blocking layer; and a thin film transistor formed on one side, deviating from the light blocking layer, of the first blocking layer. According to the array substrate, the lining substrate, thelight blocking layer, the first blocking layer and the thin film transistor are sequentially arranged in a stacked mode, the process is simple and easy to operate, and the light blocking layer is madeof the flexible material and is not prone to breakage due to bending and other operations so as o ensure the shading performance of the array substrate, so that the TFT characteristic is improved. 本发明涉及显示领域，公开一种阵列基板、显示面板、显示装置及
