The invention provides a thin film transistor substrate and a manufacturing method thereof, a pixel structure and a display device. The manufacturing method of the thin film transistor substrate comprises the steps that a transition layer is formed on an underlying substrate by using the material including the metal target material; the oxygen is piped in the process of forming the transition layer so that the metal target material is enabled to be oxidized to form a light absorbing layer capable of absorbing light; a source-drain metal conductive layer is formed on the light absorbing layer;and the light absorbing layer and the source-drain metal conductive layer of the preset light transmission area are removed through the etching process. The light absorbing layer is manufactured in the non-light-transmission area of the underlying substrate so that light reflection of the underlying substrate in the non-light-transmission area can be reduced and mirror reflection of the external surface of the TFT substrate to the ambient light can be reduced; meanwhile, the metal oxide film layer can also be used as the light shading layer to shade the light for the position requiring no light transmission so that generation of the photo-generated carrier of the active layer can be reduced and the characteristics of the TFT substrate can be improved; and the manufacturing method is particularly suitable for manufacturing the narrow-frame and / or curved-surface display component or display device.
Description
technical field [0001] The invention relates to display technology, in particular to a thin film transistor substrate, a manufacturing method thereof, a pixel structure, and a display device. Background technique [0002] The solution of the existing four-sided narrow border or even borderless display panel is to place the thin film transistor substrate (ThinFilm Transistor, TFT substrate for short) on the viewing side, and the color filter substrate (Color Filter, CF substrate for short) on the backlight side, which can greatly The bonding frame of the printed circuit board (PCB for short) is greatly narrowed. However, the metal electrode lines of the array substrate (Array) reflect light, especially when the external light is strong, the specular reflection formed on the outer surface of the TFT substrate is relatively serious, which interferes with the outgoing light of the display panel (Panel), thus affecting the display. The screen display of the panel. For the refle...
