Abstract

The invention discloses an array substrate and a manufacturing method thereof, a display panel and a display device, belonging to the technical field of display. The array substrate has a display area and a non-display area around the display area, the array substrate includes a base substrate, and gate patterns, interlayer insulating layers, flat patterns and source / drain patterns sequentially arranged on the base substrate wherein, the flat pattern is complementary to the source and drain patterns in the display area, and the flat pattern has a first slot for accommodating the source and drain patterns in the display area. The invention improves the flatness of the array substrate by arranging in the display area a flat pattern complementary to the shape of the source and drain patterns in the display area, thereby improving the color separation phenomenon.

Description

technical field [0001] The present invention relates to the field of display technology, and in particular, to an array substrate and a manufacturing method thereof, a display panel and a display device. Background technique [0002] Organic Light-Emitting Diode (OLED), as a current-type light-emitting device, has the characteristics of low power consumption, self-luminescence, high color saturation, fast response, wide viewing angle and flexibility. It is increasingly used in the field of high-performance displays. The current OLED display panel generally adopts circular polarizer (English: Circular Polarizer) to reduce the external reflected light, that is, the circular polarizer is attached to the light-emitting surface of the OLED display panel, and the circular polarizer can reduce the environment entering the OLED display panel. The amount of light emitted from the light-emitting surface after being reflected by the internal structure of the OLED display panel. [00...
