Abstract: The embodiments of the present invention provide a thin film transistor (TFT) device, a manufacturing method thereof, and an array substrate. A gate electrode comprises a first sub-gate electrode and a second sub-gate electrode disposed on different layers. The first sub-gate electrode is located between the active layer, the source electrode, and the drain electrode in a film thickness direction of the TFT device. The second sub-gate electrode, the source electrode, and the drain electrode are disposed on a same layer. The second sub-gate electrode comprises two gate electrode metal patterns. The two gate electrode metal patterns are spaced apart and electrically connected to a same scan line and simultaneously charge the first sub-gate electrode.

Abstract: The present application provides a conductive film, a manufacturing method of the conductive film, and a display device. The present application prevents refracted light by using a first metal layer to fully cover a second metal layer of a middle layer, thereby fundamentally solving black level stripes caused by lateral etching of the second metal layer.

Abstract: The application provides a color film substrate, a flexible liquid crystal display panel and a preparation method. The color film substrate includes a flexible substrate, a photoresist layer, an alignment layer and black matrix walls. By disposing the three-dimensional black matrix walls with liquid crystal-holding chambers on the color film substrate, liquid crystals can be fixed in the holding chambers for avoiding the uneven cell gap caused by the displacement of the liquid crystals. Thus, the application solves the problem that an existing flexible liquid crystal display panel has severe displacement of the liquid crystals under stress.
