Abstract: A method for manufacturing a thin-film transistor (TFT), an array substrate and a display device are disclosed. The manufacturing method includes: forming a photoresist layer provided with a completely retained region, a partially-retained region and a completely removed region on a metal film by a half-tone mask process; forming a source/drain metal layer by etching the metal film under the cover of the photoresist layer; removing the photoresist layer in the partially-retained region; forming an active layer by patterning the semiconductor film; and removing residual photoresist layer.

Abstract: The embodiments of the present invention provide a color film substrate, a liquid crystal display panel and a display device; wherein the color film substrate comprises: a basal substrate, a black matrix and a plurality groups of color filters located on the basal substrate, and a planarization layer located on the black matrix and the color filters; each group of color filters comprises a red filter, a green filter, a blue filter and a blank region defined by the black matrix; the planarization layer filled in the blank region serves as a white filter; wherein the color film substrate further comprises: at least one linear height compensation component located in the blank region; the height compensation component and the black matrix are arranged in a same layer. In this manner, the arrangement of the white filter does not require adding one more composition process; moreover, at least one linear height compensation component located in the blank region is added, while the height compensation component and the black matrix are arranged in a same layer, thus an additional composition process is not required; furthermore, the height compensation component can serve as a diversion dike to enhance a flow energy in the horizontal direction within the blank region for the planarization layer, thereby simplifying the manufacture process of the color film substrate with a red filter, a green filter, a blue filter and a white filter, while improving the flatness of the planarization layer.
